Hello Thomas,

There are a few companies that are using these LEDs in their products. Most however are using an LED out of Japan that is less expensive.

There are many different levels of lights available from Luxeon. Small - 1 lumen out, Mid-level - 20-40 Lumens out and High - 120 Lumens out. Most companies are using the 1 Lumen LED and putting 140 of them in a light.

For the light I produce (ML-155), I am using their brightest LED (approx. 120 Lumens). The cost is approximately the same once enough LEDs are stacked up, but the packaging is much smaller.

A few ops have purchased the lights I produce and are now using them. The cool thing about LED lighting on Steadicam is the very-low current draw. A well designed light can pull less than 700ma. That is less than a monitor.

James

powered perfectly off the sled... 4pin xlr in

one shot was a 1minute 30 second long shot through a crowd where i had it turned up to maximum + diffusion.. my pag lockon 20 Nicad lasted 4 takes

it had a dimmer... and a set of switches so u can turn segments off.. making the image less flat

there was a panasonic DVX100 camera onsight and there s some stills off that... progressive scan.. wicked little thing

Hi Thomas

I'll probably get hung drawn an quartered for this because it sounds like a commercial but James' lights are brilliant (literally B) ) and we are getting good responses from anyone who needs an on-camera light (not just news).

The Kisslight is also an excellent design and really well thought out including filter trays etc. and light too. We will have both at IBC for those interested.
