Lowel LED Studio, new design still in development but performance may be an issue.

www.lowel.com

In keeping with the typical Lowel approach to lighting these units look solidly built and sport standard features without unneeded bells and whistles.  The main body made of formed steel looks like a carry-over from the Lowel florescent fixtures refitted with LED panels and standard DMX hardware.  I think these may be the only working prototypes as the serial numbers were “NAB2011001”, many changes may be in store before these hit the market.

The fixtures are shown in two sizes, 250 and 450 which I think refers to the number of LEDs used. The LEDs are SMD low power LEDs and were only shown in 3200k configurations but the interim brochure shows a 5600k model as well.  The most unique thing about these units is the integral honeycomb-like reflector system.

The reflector system is made of mirror coated plastic and its many little “chrome” wells provide an aperture for about 4 LED emitters. Curiously though, the walls of the wells intersect some of the LED emitters and more odd is that the wells do not fit tight to the circuit board thus allowing light energy to be trapped behind the reflector lowering output and causing unwanted internal reflections.  Maybe this issue is just because of the quick mockup for NAB but I would think this wasted light energy could be recovered if the reflector fit the LED array better.

In measuring the light output I found my readings well below the brochures clained levels. As I was testing another gentleman with a Gossen light meter also measured the output and basically agreed with my findings… the brochure lists 657fc at 3’ and the best we could muster was 550fc at the same distance from the LEDstudio 450. Given the ambient light levels in the Lowel booth this is a big discrepancy that I hope the production unit can rectify. Our reading of 550fc is a decent performance but not anything to write home about given the size and cost of this unit. 

This unit was also one of the few where I was able to measure falloff. The other light meter toting fellow had an interest in performance at 2 meters so we both measured the LEDstudio 450 at 150fc at 2m, a whopping drop of 400fc in only 3 feet!

Overall impressions have to be all covered by the caveat that this is not a production unit and the issues observed here might be rectified before this unit hits the dealers, if not Lowel will have a problem on their hands. Otherwise it looks like a solid, middle of the road fixture with a good build and workhorse features. Stay tuned to see how it develops.

Lowel estimates the units will be in dealers by July 2011.

Here’s the numbers:
LEDstudio250  400fc@1m   3200k
LEDstudio450   550fc@1m  150fc@2m  3200k  $22-2400.00

 

Autocue, rebranded Chinese panels still a disappointment by any name.

The Autocue booth was front and center at NAB and featured several rebranded Chinese LED panels. I’m about 99.9% sure these are LS brand panels with a simple “Autocue” sticker added for branding on the back.  Now the “LS” panels aren’t the worst of the breed for 1x1 LED panels but there’s nothing new here to report. If you’re looking for this type of fixture at this quality level just seek out the cheapest supplier/rebrander because they are all the exact same. For details on the build and features of these Autocue panels please see the “LS” review coming here soon. For continuity’s sake I tested the brightness of the Autocues for comparison to their parent panels and they seem to fall within the normal output expectations for then Chinese 1x1s.

Arri L-Series LED Fresnel...Look at the shadow picture, what more needs to be said!

(download)

www.arri.com/l-series

I went to NAB really jazzed about finally seeing the mysterious Arri fresnel and I wasn’t disappointed. Just one look at the shadow picture I took tells the whole story, Arri nailed it. True, hard, single shadows.  I got lucky Thursday morning as I was the first person to the Arri display when they were just taking the new units out of their secure storage area ("Area 51" I suspect) so I got a lot of time to fondle and ask questions.  The units on display at NAB are the only functioning prototypes Arri has in the world and I was told that the final production model will have some differences but the basic foundation is in these units. I was told that they were actually programming the processors on the show floor the night before to improve performance.  Arri plans to have the units on sale in North America by late fall 2011.

From the pics you can see these units are quite large, the “-7” name refers to the 7” fresnel lens system which looks like it can share all standard 7” accessories like gel frames and barn doors. The focus range is 15-50 degrees. Units are available in fixed colour temperature or with fully adjustable colour. The fixed colour units draw 250watts and the adjustable unit draws 220watts.  The units are either passively cooled (see the MASSIVE heatsink in the pics) or actively cooled with a large rear mounted fan.  The units contain 84 RGB style LEDs but they would not tell me the makeup of the RGB layout or if they contained any W,A or Y LEDS.  Arri staff commented that the output was under a 1K tungsten fresnel for comparison.

The L7-C is the fully colour adjustable unit and features a side panel multi-display control that allows for dimming, colour temp, and +/- green adjustments.  In this module you can also invoke party colours and control their hue and saturation.  The unit offers two memory settings to recall your favorite mixes.  There were a pile of other settings but I did not get a full rundown on these as the crowds were starting to form.  The L-7T is the 3200k fixed colour temp and its side panel offers dimming and some process control which I did not get explained to me.  I did not see a daylight unit but was told they will be available. Focus is handled by a large hand knob near the front of the units.  The units featured a USB port on the back panel for processor upgrades as well as standard DMX control.

Overall these units are a home run for Arri and should make the studio guys very happy. The units are solid and extremely well built, as one would expect from Arri. The colour looked great and the shadows are unbelievable, without a doubt the best LED fresnel at the show.  If you want one I’m sure the line will be long.

Here are the numbers:
L7-C (colour adjustable) $2990.00
L7-T (single colour 32 or 56K) $2890.00

The L7-T (3200k) at the midpoint of its zoom range showed 410fc@1m

Dexel LED, solid looking but not a lot of information.

www.dexel.com

Well the nice people from Dexel are from Argentina and only speak Spanish, me not so much, so the info I could get was very limited.  Currently their fixtures are not available in North America but they are seeking a distributor, inquiries can be made on their website.

Dexel has four main LED products, a high power panel, 5mm LED panel, Red Head style high power LED and a LED Fresnel style fixture.  The units all look very well constructed mainly using aluminum and stamped steel, beefy screws and thick yokes.  They felt solid and professional. All panels featured local and DMX control as did the Fresnel fixture. The “red head” style fixtures only had local dimming control.  I couldn’t figure out how to work their DMX system but an English manual probably would solve that issue.

The Fresnel fixture was not functioning but looked as sturdy and well made as the panel products.  I believe they were trying to tell me that it was a non-functioning mock-up but it looked pretty production final finish to me.

The high power panels all had a very large fan on the back and in the show floor din I couldn’t hear any sound coming from the fixture but I’m sure they make their fair share of fan noise judging by the airflow I felt coming from the exhaust vents on the fixture.  The high power panels are rated at 6000k and a drop in diffuser and 3200k dichroic colour changing are available as options.

The ‘red head” style fixtures were interesting, made from a solid aluminum spun rear housing and a standard accessory looking front bezel I bet these would integrate quite nicely with an existing “red head” kit and share the hot light accessories.

No prices were available but they promised to send me an email with additional info and costs.  I would have liked to learn more here but the language barrier was tough and I was dead tired as I hit this booth on the way out Wed. evening so I kind of rushed things.

Overall impression, very good. If these units have a reasonable price and a decent US distributor can be found they may find some good traction in the market.

Videssence, claiming the most powerful light throw available in their class, too bad they don’t make the grade.

(download)

www.videssence.tv

I visited the Videssence booth where they had their primary LED fixtures on display.  The ExceLED 24, 50 and 100 models named so for their wattage listings.  Now Videssence claims these units have the most powerful light throw available for their wattage, a claim I wasn’t able to substantiate but they defiantly have some punch.

Each unit is based on a primary 9 LED cube module with what I estimate to be a 10 degree lens on the LED.  The 25 watt unit sports one LED cube, 50watt two LED cubes and you guessed it the 100watt four LED cubes.  Construction is of bended/formed aluminum with a black powder coating. The lensing seems very narrow and served to throw the light but I’m not sure if this is a positive given their intended design as a studio fixture.  The booth staff demonstrated the 50watt units throw by shooting a pretty strong beam about 60’ onto the ceiling of the LVCC.  Great throw but probably too narrow a lens for studio use unless you’re trying to give the talent sunburn.

The units come standard in 3200k and can be ordered in 5600k if needed. A claimed CRI of 85 seems pretty honest compared to the baloney listed the other LED sellers at the show. Standard units are not dimmable but dimmers are available by special order.  The 100 watt unit on display had on-off switches on the back panel to control each of the four LED cubes, a kind of odd dimming system if you ask me as turning off cubes will change the pattern and evenness of the beam.

The units are AC powered only and do not offer DMX or any external control.

One unique feature in the 100watt model is the ability to pivot the four LED cubes to change from flood to spot configurations. Now this was a pretty lo-tech approach with a gear wheel/internal screw mount moving the center of the cubes in and out to concentrate or spread their narrow beams. It didn’t look very effective but the units were so crowded together it’s hard to tell. 

Even though they were bright and punchy, which I’m sure is due to the narrow lens, I didn’t like these units at all.  They are big, ugly, low-tech and way over priced for what you get.  They look like something made in shop class at your high school, and sure looks aren’t important if performance is there but the ExceLED’s don’t make the grade in this department as well.  Videssence takes an old school approach to these units and it shows, no DMX, key features as options that are standard pretty much everywhere else and lens configurations that seem inappropriate for the primary in studio use.

Overall impression, underwhelming.

 

The numbers:
ExceLED25  5600K 1400fc@1m $1200.00
ExceLED50 3200K 550fc@1m $1900.00 (different lens I suspect)
ExceLED100 $3500.00 (couldn’t get a reading of fc as the unit was so crowded in with others on the side of the booth I couldn’t reach in to take a reading)

The “China Crap Panel” et al.

The bitterness of poor quality is tasted long after the sweetness of low price is forgotten! Heard that one before?

Before I engage this rant please clearly note that it has nothing at all to do with the fact that the manufacturers are Chinese!  Love the Chinese, hate their lights.  Some products and components made in China are great, these lights aren’t one of them.

There was a massive amount of Chinese lights on the show floor at NAB 2011 and pretty much they all exhibited the same downfalls. I just can’t get past the fact that all these manufacturers showed pretty much the exact, I mean exact…sorry EXACT same light designs, did I say exact?  Over a dozen booths showed the same 12”x12” yoke mounted panel with 5mm self lensing LEDS “ala Litepanels” 1x1 design.  I know the Chinese are renowned for their ripping off of popular Western designs but really now how about just a drop of originality.  Haven’t they figured out this design has been done to death and pretty much outdated already?  Not one of them brought anything new to the design, well except for maybe low price.

I tried to ask each of them why their design seemed to be everywhere at the show but never really got a good answer. Some stated they were the originators of the design, some stated they used better components, some stated they had innovations like bi-colour or a dimmer and my favorite was the lady who told me that they built the original units for Litepanels and they were pissed off that they weren’t getting credit for it...hmmm. 

Anyways these units not only look the same but share similar defects.  Of primary concern is the poor colour quality, low quality electronics, questionably build quality and the lack of consistent performance between identical models of the same brand. 

At one booth I measured the light output of their standard panel then checked another just two feet away and found a 100fc difference..me thinks somethin’s wrong so I double checked…same results.  This new revelation sent me back to booths I had already checked to see if this variance between panels was a common issue.  For the most part the panels of other booths were consistent between samples to an acceptable degree, 10-20fc between like samples seem reasonable given the unscientific testing environment. That being said a few manufacturers were way off the mark one even showed a 300fc difference, but as my review will show later I think this outfit was the worst LED light in the show.

The electronics of these units also is of concern, most seemed to use hardwired construction techniques with no modular design or removable connectors for ease of servicing.  I couldn’t see every internal design but one the ones I could see everything just looked like a big ball of solder and black tape.  The circuits also looked very basic, not much voltage protection or signal processing going on.  For the units that used battery power I would have to wonder about low voltage protection as well.

Colour was a big concern for me since it was the impetus for this blog and well these “Crap Panels” did not leave me wondering. They SUCK! It’s pretty damn hard to make fair colour comments without test gear but when some of the panels are so blue that the booth staff describes the colour as “midnight sun” at 5600K I gotta start wondering ‘cause I live in Canada and I’ve seen the “midnight sun” many times and trust me it ain’t that blue.  Take the colour comments as my opinion because they’re totally subjective.

Build quality is all over the map, stamped tin to machined aluminum, plastic nuts and Velcro to millions of tiny screws.  With a few exceptions I don’t think these panels will cut it in a professional production environment.  I think most of the raw enclosures are fine but it’s the human touch points where quality really falls apart.  Dimmers, colour controls, yokes, power connectors and the such.  All seem weak, under sized poorly mounted.  One panel actually had the dimmer direct soldered to the PBC and the dimmer knob shaft was unsupported poking through a hole in the back panel, how long would that last…five minutes on any of my sets.

Never mind all my complaining the big issue really is service. NOT ONE OFFERED USA/CANADA SERVICE OPTIONS! So when your $200 light breaks what do you do? I’m sure the manufacturer thinks you’ll just fix it yourself or throw it away, or are they really marketing disposable lights?  Now again, trying to be fair, I am including the Microbeam and IKAN  LED panels in this “Crap Panel” category and these two companies offer service but they are just resellers and probably just suck up the costs of repairs in their customer service budgets.  The true “Crap Panel” manufacturers offer no service PERIOD!

Still not deterred and want to buy a “Crap Panel”, good luck.  Most manufacturers only deal via the web and language on their websites is an issue if you’re an English only speaker.  My big wonder is payment, they don’t use PayPal but rather all seem to request the TTL system of advance payment in full via bank transfer. This is a system used mainly for business to business Western Union style transactions; problem here is you never really know who you are sending your money to.  Two different exhibitors actually provided me with their personal bank account info for transfers rather than the company accounts listed in their brochures….run away silly Westerner save your money.  I have heard of several people on DVinfo.net having good experiences with some of these dealings but I’m way to cautious to send money into the dark abyss without a way higher comfort level of whom I’m dealing with.

Enough negative chat for now, on with the reviews.

 

Apologies for Posting Delays

Sorry for not getting the info up here in a timely fashion.  I returned from NAB to a full show production on Saturday and an ill baby on Sunday, so free time to post has been a killer.  Our little baby Kate has taken sick and it’s been sleepless nights and anxious days for Mommy and Daddy but all should be well soon.  I promise to get the majority of news up as soon as I can, by the flood of emails it looks like there is a lot of interest in the topic.  Hope I can do it justice.

DeSisti, Why Did You Even Bother Coming to NAB?

www.desisti.it

This outfit is a puzzle. I went to their large booth to find all the lights turned off and the staff all sitting at a table drinking coffee and chatting.  After fumbling about myself trying to turn a few lights on someone finally came over and asked if I wanted something, well I want some lights turned on of course? 

I was holding my light meter in my hand and the gentleman gestured to it and told me that pictures were not welcomed in their space, when I explained it was a light meter he told me that no lights would be turned on unless I put it away...hmmm the alarm bells are already going off. Well I put my toys away and on come these underwhelming lights.

I was told that these were their old tungsten fixture enclosures retrofitted with a new LED light engine and it looked like it.  The 90 watt model was demoed that they claimed matched a 1K Fresnel, even without a meter I can tell you it wasn’t even close.  Horrible light output with a visible central hotspot, when zoomed through the full range I could barely tell anything even happened from full spot to full flood.  As a Fresnel this product is a full FAIL!  As for shadow rendering, my hand placed in the medium beam cast a number of easily visible shadows.

I couldn’t get any prices either.  Maybe DeSisti had a rough night at the tables and should have just stayed in the hotel.

Elation, DJ lighting comes to television.

www.elationlighting.com

I have a bucket load of experience with Elation lighting projects through my years as a designer of nightlife environments (that means bars in normal speak) and always liked their great value, advanced innovation and reasonably good quality...but hey it’s still a DJ light being adapted for broadcast use.  The Elation products shown at NAB are all good in the right environment but I don’t think that lighting sets is one of them. They showed good brightness and decent build but the colour was way off, crank up the Kesha and we’re set, crank up the cameras and we’re screwed.  A rep in the booth was expounding the virtues of the lights and showed me numerous photos of recent set design projects where the lights were used, all beautiful vibrant purple and green and red back lights..’nuff said.

One neat Elation light was the WW Tone light utilizing a single 100watt warm white LED. It didn’t show the Fresnel like properties of a single source fixture but it did have a nice even beam and the shadows weren’t too ugly.  Also to note is the TVL2000 fixture which is the Elation version of the ubiquitous Chinese knock-off litepanel that every second booth seemed to be showing (let’s call this the “China Crap Panel” for now- more on this later). The Elation version was a much better quality version of the “China Crap Panel “with a digital control panel and DMX data connectors.

Just to add a note here to be fair the Elation staff were very helpful and knowledgeble and never once claimed any CRI rating or colour quality and their literature doesn't make any unrighteous claims either.  I think they know their product and how to use it in the right setting.

Here’s the numbers:
TLV2000 3200K 400fc@1m $600.00
WW Tone 3500k 440fc@1m $1000.00
Elar180 3500k 1400fc@1m $1200.00 (60x3watt LED)
Elar216 RGB+W 280fc@20’ $1500.00 (72x3watt LED distance an estimate)
