Does anyone know the CRI (Color Rendering Index) or Degrees Kelvin of the light output of this LED source (I plan to use oil painting nocturnes)?

Concerning the output of the led source. The light source is AAA battery, its light is amazing. It is extra bright. Never seen before. Try you will like it.

http://anyray.us/default/catalogsearch/result/?q=A1700Y I went to this webpage. The little boxes they are in says nothing about the kelvin color temperature rating.

2700K color temperature and color rendering index of 80 are close to as good as LED bulbs get. To completely match incandescent, LED bulbs will have to reach 2700K and 100 CRI. But I have a number of bulbs with 2700/80 that I am satisfied with in terms of warmth vs incandescent, especially considering the superior bulb life, reduced waste heat output, and lower energy costs.

Hi, Thank you for contacting us. This would be great for that type of situation. Because the LED lighting is coming through the mirror it provides useful lighting great for personal grooming and makeup applications. Unfortunately we do not have the lumens for our LEDs only the kelvin which is 6000. 6000K on the color temperature scale is close to daylight and is a bright white light. Have a great evening. Regards, Howard - Lighted Image.

I believe right around 5,000 Kelvin. They are white with slight blue tint. No brighter than holagen, but in my Windstar with no other light they do reach noticeably further. I won't go back to old holagen lamps. Just better LED's.

Just gathering info from hexbright.com website, (led is "CREE XM-L bin U2"), and cree.com product info 'http://www.cree.com/products/pdf/XLampXM-L.pdf' the color temp is around 6500K, cree says typical CRI is 65 for this temp. You know much more about this than I do to even ask this. I know there were lots of light geeks on the kickstarter board discussing this, so someone knows this. Ask at hexbright, they're friendly and helpful. I have several of these and love them.

I don't see the kelvin # on this package, it may be on the back, does any one know? Light Bulbs are rated for Color Temperature, measured in kelvins. In my kitchen I prefer a `daylight' white light at about 5000 to 5200 kelvins. You'll notice the difference immediately if you mix bulbs in a multi-light fixture; one very white bulb makes the yellow ones seem REALLY yellow! Here's a webpage with an explanation and chart.http://www.lightbulbsdirect.com/page/001/CTGY/ColorTemp

As bright as a 100 watt incandescent bulb. Draws 27 watts, color temperature 6,500 Kelvins.Not as bright as you seem to want - not a directed beam.Bill

Ballasts do not determine kelvin temperature (or the color of the light)......it's the bulbs :-)

To my knowledge, it is 4200 K with a light output of 3350 +/- 300 lumens. Higher temperatures do not mean brighter bulbs. Higher temperature bulbs put out less light.

How about this research Jerrey H, from an email I received from Paul C Buff Technical support:RE: AB 800/1600From: "Info at Paul C. Buff, Inc." <info@paulcbuff.com>To: Doug <dwdallam@yahoo.com> Hey Doug,Thanks for contacting us! The reduced power color shift on both units will change by about 2-300 degrees kelvin. Let us know if you have any other questions!Thank You!!!TashaCustomer ServicePaul C.

For the 30W unit, Zitrades lists the total (R+G+B) output as just under 1300 lumens. I would estimate the white level to be <2700K.

I would guess 3000 Kelvin for the color on the LED. The lumen is equal to a 25 Watt PAR 36 incandescent well light and 20 Watt MR16 Wide Flood light which we replaced with the Paradise. I've installed 13 of these lamps and am very pleased with the results. No issue with installing and for the past 4 months no problems with the fixture. I would say 2 meters would not be a problem you'll just need to adjust the angle of the light head.

I don't know the answer. I use this to run 4 trees of four Electro 86 LEDs each. I've never tried to really tweak it as I primarily use single solid colors.

I originally purchased multiple types/brands of LED units for different rooms which have different lighting. It only took a couple days before we decided the performance and quality of the Starpower LED units was exactly what we were looking for. We replaced all of the other units with these and could not be happier. The 2700K output (color) matched our regular flood bulbs exactly. Could not be happier with them.I was surprised to see how far the dimming goes down (and there is no humming sound from these units). As for your question, 5% would be about right if you asked me.
