LED lightbank?

Anyone try these? Looks nice for a small and practical light source and a good price for it. My concern is it may be a bit harsh so anyone ever try it? or use anything similar?

Those look really nice, at least on paper and in pictures. I think they are a new product so there may not be any users yet. LEDs tend to focus their light in a beam so the only quirk to pay attention to might (might) be that the light doesn't throw a really wide pattern. This may actually be a benefit as a source that large is harder to control. They mention this effect in their literature as the 20 degree beam width of the individual LEDs. I wouldn't worry about it since it is easier to diffuse a hard light than to focus a soft light.

Thanks for pointing this out. It is far cheaper than other LED solutions.

One question to ask the manufacturer is what type of barn doors it uses. The pictures show both flat black and mottled shiny.

it is hard to understand how they can sell the mic light (48 leds) for half the price of this one (500 leds + case).

seems the barn doors came black and you can add the reflective stuff if needed.

too bad , it work only on main AC, would be nice with a 12V plug for use with a car battery for example.

It may work with a small power inverter. Since it isn't dimmable, it shouldn't need special power requirements. At only 40Watts, it can likely use a small inverter like those made for laptop computers.

The mic light seems a bit high in price, but $400 for an LED panel with barn doors and 5/8" spud isn't bad. Fluorescent is still cheaper, but this might make a decent backlight or a key in a small interview setup. The focused nature of the LEDs might make something like this a good companion to softer fluorescents.

Sorry to break anyone's bubble but the mic lights are a fraud in my opinion. I bought one at NAB. I have since bought two more from an ebay selling company in China. The one from NAB was $149.00. The ones from China were $5.00 and advertised as tent or camping lights. Exactly the same light-----period! We have been ripped off on the mic lights. They were just repackaged tent lights.

P.S.: With shipping the China lights were just under $12.50!

The question still stands, Mike: do they work worth a darn (the $5 mike lites)?

Of course, I've been looking into LEDs as a product for a while and I've seen all the products flolights is carrying at the sources of where they get them here in China. I never even considered the "uflolight" as I call it as a serious product. If I were going to do a ring light it would fit over the lens with some sort of speedring adapter big enough to fit around all the different kinds of lenses in the world. The idea of putting it on the mic has merit in some ways but there are so many differences in mic's and sizes on different camcorders that its not so practical when you really get down to it.

The other 500 LED panel I rejected because it has no dimmer and no built-in battery capability so I would have to engineer that. Bank select switchable dimming on a LED panel? Silly for that price range and dimming LEDs is not that hard to do.

One other thing that's suspect on this offering: It claims "500w equivalent of light" for drawing 40w. Doubtful. Let's do the math on this. That would mean that all the LEDs together were functioning at 250 lumens per watt (considering 40w draw on this panel and 10,000 lumens normal output for a 500w tungsten bulb at 20lpw). Impossible by today's standards. The best LED in a laboratory is 110 lpw and thats experimental stuff not out on the market yet. A good estimate is that it probably puts out about 2000 lumens.

To compare, a 2 bank 55w flo unit puts out a little over 6000 lumens so you would need 3 of these panels (IMHO) to equal a 2x55 unit. Let's see: Cool Lights 2x55 = $169. 3 Flolights 500w LED panels @ $399 ea = $1200 roughly. Are fluorescent and HMI dead yet? You decide based on your budget.

As Marcus stated before, the LEDs are very directional so you tend to get more of a spot effect out of a panel like this, not so much of a soft scattered light like fluorescent--so it all depends upon what you want.

I am serious about offering something like this by next year and I decided it's better to build a scratch solution from the ground up to keep the costs low. I think a dimmer and battery are mandatory for an LED panel and I really don't understand the use of this 500 LED light for anything other than in a studio or if you're willing to do some adaptation yourself with something like a tekkeon battery. But, let's face it--at $399, then adding a battery, you're really getting up there. I would expect to offer something like this for $399 with a battery and built-in dimmer and perhaps even a bit under that. And $399 is the "intro" price...

I actually have the circuit board prototype with dimmers and all--just waiting for a battery system and a suitable, attractive fixture case and mounting.

I think they are pretty cool. A decent amount of light from a small unit, with long battery life. We are filming in a submarine in about February and thought they might be nice to stick in small areas where we can't put other lights. You are not going to light up a stage with these things but in close locals they are neat lights.

Hi Martin,

Some people think so as long as you gel them because they are a high color temp and a bit blue for sure. Add a bit of CTO to your taste.

Yup, they are about 5600K and the mic light was supposed to come with something to reduce them to 3200k, but of course in was not in the box and there was no response to emails to the company. You would have to color correct them. Still pretty cool for the money, even if you just want to light up your tent! :)
