I just made the STUPID mistake of looking at the damn thing in dim night time house light. I am still seeing trails 20 minutes later.
The light is at an odd 4600 color balance and does seem to have a very slight greenish hue although nothing that could not be corrected in post or white balance compensated. Diffuser works well.
At 8 feet it appeared to work as a good fill light in daytime indoors and a respectable ENG interview light. At night I was able to light up the interior of my house at 35 feet. In auto mode I could tell that the camera would go dark when the light was switched off, then you could see the gain come up quite a few steps which gave me a sense that even at 35 feet the light at least knocked the gain down significantly.
My goal for a light like this would be to have just enough light to remove the video noise. I think too much more than this would make the dancers who love dark hunt you down and kill you in the street in a drunken wedding party stupor.
Even on the 4lux light-challenged HD1000u (actually not bad unless you're used to an old Sony DV cam) this thing popped it up to at least seemingly eliminate most of the noise at 15-20 feet. I need to check it on a monitor and not just the flip. Soon I will hopefully be moving my video hosting from the horrible Youtube to vimeo at which point I may post some equipment tests.
Hank, if you're out there I would be willing to mail this to you to do a test between your handy, dandy Bescor lights. I'm sure the Bescor lights will beat it but it would be interesting to see by how much.
I think LED is the future and I wish I could see the LitePanel Micro compared to this at 10x the price. I'm sure the Micro has better balance and the dimmer is huge. An Amazon review described them as similar in brightness but?

Regardless, the one thing I can say for sure is that this little thing is worth more than you pay for it. The fact that you can add 3 more via the shoe mounts and still have only $120 bucks in the rig is intriguing. You could switch them on and off as your "dimmer" control.
Ultimately I think I would rather go with a more Pro product but what if they are only 10% apart? Not likely... This will probably supplement the built in light on our B,C,D roll Vixia 30 cameras which at 3lux do quite well in lower light.
Very clever little device and the 3 shoe mounts and i
ncluded additional shoe bracket pave the way to a future of lower mid level pro products.
There's really no reason the Micro should be much more than $150 if more people were buying it.
Best,
Todd
