Is this light UV B with a 290-320 wavelength?

I pulled out the package insert, and it appears to function only in the blue wavelengths of around 425-500. It states "the Syrcadian Blue provides maximum therapeutic intensity, while minimizing the normal side effects experienced with high brightness, full spectrum light therapy. Full spectrum side effects include blinding glare, headaches, dizziness, and even nausea'. Hope this helps you!

Before considering, check on the safety of the blue light spectrum on the eyes. This may be a discussion you should have with your physician before using a device such as this product.

Equivelent to 500 watt halogen but the light is a pure white not a brownish.

450nm is not UV, that is visible blue color. UV (ultraviolet) is less than 400nm in wavelength. Fluke makes a really good UV light that emits 395nm. But it costs over $50.

Halogen are generally around 3200k, with standard incandescent bulbs being around 2900k.

I don't think there is a UV Light in here. I bought this light because of the LED lights... Good luck

Hi Colleen. I looked at the box and it doesn't say anywhere on it about being UV. So I don't think it is. Hope this helps

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

Check the specs or the camera--wavelength against wavelengths emitted by light.

It is supposed to be a full spectrum light including a little UV. No need for grow/veg settings, but you can buy another one with more blue if you really think you need it for veg (like the Lighthouse Hydro Veg/Clone LED Grow Light, 90-watt ).

I doubt led can output UV for plants and I would say the spectrum is 4100 K.

3200K is more of a blue light.. 1700 and below would be a much warmer light (yellowish).

I would google ultraviolet vs led and read the answers. A good one was this one www.nsinails.com/.../led-vs-uv-by-rise'-c...Hope that helps!!Crystal

It's a black light, like the kind that makes certain colors like white glow brightly, only it's not an incandescent bulb, it's 12 LED's which doesn't give off much heat energy, so batteries last a lot longer. UV-A is a color of wave length that is outside of our visible range. Mine arrived kinda silver/chrome in color.

I'll try to answer this question even though the wording is odd. If you are asking where on the color spectrum they are, they are 6500K on the color temperature spectrum. This is similar to the color of daylight on an overcast day. Not really on the blue or orange side of the spectrum. Pretty close to white light. I can't find a wavelength chart that breaks down the distribution of wavelengths for these bulbs.

Yes I can see the UV light . My room is 13' x 15'. I turn the UV light off at night
