Hello, does it state what spectrum of blue light this is on in nanometers? (nm)

Nothing on the box indicates a spectrum. It's a low-lumen blue light that is great outside a back porch, for example, enough to light the porch and doorway.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

I would say the light is closer to 6500k (more blue than white). I found this annoying because even though I enjoy white light for daily tasks it is too white/blue for me to keep on during the night. It is also a lot brighter than I expected!

It doesn't say anything about UV on the package. The graph shows little output below 400nm, <5% daylight. It's equivalent to a 10w fluorescent and a 50w incandescent.

No. This light projects light at Light Spectrum: 460nm, 610nm, 630nm, 730nm;(according to the manufacturer), which is ideal for plant growth. Ultra violet light is lower on the spectrum, 10-400nm (according to wikipedia).

thank you for the question actually I returned it back as it didnt match my requirements using it in big room, regarding resolution and illumination (lumins units) wish to help you more :)

From what I have read these meters do not accurately measure LEDs. I have LED lights and the meter reads 4500 to 7000 lumens but as you say that is a focused spectrum. My plants spend part of the day in natural light and the readings are much higher in the greenhouse.

254 nm (nanometers) is in the ultraviolet part of the spectrum. Exposure to it will kill bacteria and viruses; it will damage one's eyes.

As best I understand the question, this sort of comparison is just what the meter is meant to do: measure light intensity. What you read is what you got. Regards,AC

Good question; maybe would be clearer if you asked "color" temperature. I would expect about 5000K otherwise people would be complaining about blue garbage light.

No. Not full spectrum. 2 blues and 2 whites. I'm disappointed. I own one soon to be put up on eBay! Comes with expandable metal hang on brackets.

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 http://www.amazon.com/Lighthouse-Hydro-Clone-Light-90-watt/dp/B00E8DVMJ8/ref=pd_sbs_lg_53 ).

I have a 395nm Flashlight from Cybertech with 9 UV LEDS (Its a 3 in one with a reg flashlight, red laser and UV ) it will detect dry stains, but not wet ones. There is a good bit of purple haze at 395 though it works. 365-375 shows awesome, and I am waiting to test and make a comparison with a 380-385 one

I haven't noticed a blue tint to the lighting. So I would have to say no. I really like the device. I frequently use it for illuminating whatever I am working on without any magnification, but if I need magnification, I have that as well..

This is a BROAD spectrum white light. Earlier technologies used blue spectrum (still a white light, just a more narrow spectrum of it) because they could make cheaper bulbs for light therapy, which were originally in the $100s. The term "white light" confused some posters here, because they all appear white. Look for the terms "broad spectrum" vs blue or narrow spectrum lights.

The light(when it works) is a bluish-purple, but it works because it emits ultraviolet light. Pure UV is invisible to the naked eye.
