UV = ultra violet light, very high energy stuff. This is the stuff that causes cancer and gives you a sun burn/tan. Animals need UV light in order to metabolize a range of vitamins. This is also what causes plastics to become brittle, bones to bleech white... These lights are sold in the reptile trade to prevent metabolic bone disease (reptiles need UV to metabolize vitamin D3).
UV-B Light:
UV-B light is harmful to living things, THC has very high UV-B adsorption properties, thus cannabis evolution may have favored the evolution of genotypes that produced these THC laden capitate-stalked trichomes as a built in 'sun-screen' for protection against UV-B light rays.
I have never had issues with using aluminum foil and CFLs. Never had any problems with hot spots at all. White paint works just as well though.
/edit. This is why you want UV : great link here:

THC:
delta-9-tetrahydrocannabinol & delta-8-tetrahydrocannabinol - THC mimics the action of anandamide, a neurotransmitter produced naturally in the body, which binds with the cannabinoid receptors in the brain to produce the ?high? associated with
marijuana. THC possesses high UV-B
(280-315 nm) absorption properties.
As THC absorbs UV radiation the energy is absorbed through chemical reactions. These reactions are believed to change the structure of THC into the secondary cannabinoids and vice versa. CBD is the big one for me - creates the anti anxiety properties I am looking for.
THCV:
tetrahydrocannabivarin - prevalent in certain South African and Southeast Asian strains of cannabis. It is said to produce a ?clearer high? & seems to possess many of the therapeutic properties of THC.
CBD:
cannabidiol - previously believed to be psychoactive, or to contribute to the high by interacting with other cannabinoids, conversely the most recent research indicates that CBD has negligible effect on the high, it is however a strong anti-inflammatory, and may take the edge off some THC effects, such as anxiety. CBD as a non-psychoactive cannabinoid appears to be helpful for many medical conditions. CBD biosynthesizes into cannabinol (CBN) & tetrahydrocannabinol (THC).
CBN:
cannabinol - a degradation product of THC, produces a depressant effect, ?fuzzy? forehead.
CBC:
cannabichromene - non-psychoactive , a precursor to THC.
CBG:
cannabigerol - non-psychoactive, hemp strains often posses elevated levels of CBG while possessing only trace amounts of THC.
