Hope you wonderful people can help me find some solid answers to these questions. I’ve been considering getting some grow lights to let me keep high light requirement plants in low light areas. Problem is any “answer” I’ve found online so far has been unsourced, trash sourced, or even obviously biased, junk.

1 - Do grow lights emit UV? The type that tans us, and damages DNA? (Shockingly, most places that sell grow lights will tell you they do not...LOL)

2 - Do grow lights fade oil and watercolour paintings, or anything else like wood furniture, etc, over 20-40 years? Has anyone run a grow light for a long time in the same place and can maybe speak to fading, based on areas of wall paint, furniture, etc, where the light shines directly vs. not? Is it visible, zero fading, etc? (My understanding is UV fades colour. If no UV, no fading. But I’m actually not sure about that....maybe bright light, even without UV, can cause fading?)

3 - What is the actual power consumption and light output for your favourite low energy consumption grow light(s)? I really don’t love the idea of burning more electricity. If a million of us used, or did NOT use these lights, is that a huge power difference, or is it really still negligible, like an oven at 325 for an hour uses as much power as 1 million grow lights for 24 hrs? I’d say if it brought a million people a lot of happiness, for minimal impact, it’d be worth it. We should look at other, better ways to save electricity. But if every 10 of us that run them for a year is another ___ thousands of kilowatt hours, it’s not for me.

Thanks in advance for any helpful input, and all your great posts. I mostly lurk, but love this place! Go team r/houseplants! : )
