is it broad spectrum UVA &amp; UVB?

I don't know. It was recommended in a 6/20/2014 Wall Street Journal article that tried a variety of sun screen products that did not contain "bad" chemicals. The reviewer said "This ultralight liquid is real next-level stuff. It's 100% mineral protection with a clean, matte finish, water-light consistency (a little goes a very long way), and the sheer tint offers light-diffusing coverage and a hint of golden color." I liked it a lot, but it wasn't good for an activity in which you sweat a lot, as the tint ran onto my clothes. The Environmental Working Group has a report o sunscreens. You might see what they said about it.

Part 90 radio will be the UV6 or UV8. I much prefer the new UV8, true dual band and nice color display. Got two of themand giving away the UV6. There are slight differences in the UV6, more coverage on some, confusing yes!

There is no UV light emitted by the product. UV light starts at 400nm and below, whereas the product puts out light from the 590nm to 880nm range, well above the UV spectrum. Goggles are included with the product and MUST be used at all times, since the light is very bright.

UV light ranges in wavelength from about 250 nm to 400 nm, that said only the wavelength closer to 400 nm is purple, dont confuse this with the more familiar black light bulbs, which only go down to 450 nm and appear purple. in order to sterilize the water the UV must be at or below 350 nm which is below the limit humans can see, so what you are seeing is the glow of the gas in the bulb which appears whitish with a blue haze, This means the bulb is designed to act as a stetilizer and not to make your old black velvet 70 s Era posters glow all groovy.... also the invisible UV can cause a sunburn on your cornea so limit any exposure, this effect isnt instant it takes time and causes eye itch...

No UV light is emitted from the RedMD. We include goggles which must be used with each treatment.

Yes. I have used all Gelish products with both. LED lamps are faster to cure, 30 seconds, compared to UVB lamps curing taking 2 minutes to cure. This is the only difference. Is faster better for the price difference? Maybe if you are in a hurry.

UV-B is the UV you need to worry about, but it's in the 280nm - 315nm range. UV-A is essentially what's known as blacklight, in the 315nm - 400nm range. Starting at 400nm, we get violet, of the visible and non-ultra kind. So this 395nm light is at the safe end of blacklight. No need to worry. It's OK for lighting up phosphorescent material, but not even close to the kind of UV you get at the tanning salon.

To the best of my knowledge.....no. UV would be visible as more of a blue/violet light to the naked eye and these bulbs put out a very bright white light.

UV (ultraviolet) is NOT good for your skin (hands in this case). It would be like suntanning your face for 8 hours. There are gloves you can buy if you're going to use a UV lamp. I much prefer a NON-UV light -- for the health of my skin.

UV has a light wavelength below that of the visible range. Since these lights are all within the visible range (minus the red which has part of it in the IR), there should be no UV rays.

I don't know about this one. I use Healthy Defense Daily Moisturizer with sunscreen that says broad spectrum SPF 50 on the front.

No. LED lights and HID lights (HPS for example) emit a completely different UV spectrum. When flowering, HPS is fine by itself-as long as it is powerful enough.

It's both actually. LED is the type of bulb being used (opposed to incandescent, halogen, etc). UV is the type of wavelength that bulb gives off (UV gives it the purple color).

Hody , I use mine indoors so I don`t have any experience with UV ... it is a bright yellow , so better in the sun than black or grey chords . I love my US Wire product !

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).

No it's not a uv light. It had the appearance of a uv light because of the colored plastic cover only.

UV Clear SPF 46 is formulated for skin types prone to acne, rosacea and hyperpigmentation. UV Daily SPF40 is a moisturizing sunscreen for normal or combination skin types, which is also tinted. I assume that translates into having different ingredients, hence, the difference in price. I know there was a price difference at my doctor's office as well. Like I stated in my review, I had to exchange the SPF40 for the SPF46 because the 40 caused my face to turn red. The 46 truly is much milder for me and doesn't cause any irritation.
