incandescant produces very little to almost no UV. Flourescent of all sorts produces UV. Usually it is filtered out by a coating on the tubes. Any old plastic diffuser on a 2x4 troffer that has yellowed has done so from the UV produced by the bulbs. BLB just filters out the visible spectra. Dedicated T18 may be the better way to go, but I bought my compact tubes with Canadian Tire money.

CTM is a store script, that accrues from purchases in their store or gas bars, or when you use theier credit card, as a small fraction of all purchases. I typically accrue about $8 per month these days. I really piled it up when I had two kids in day care, and payed their fees with my Canadian Tire Mastercard credit card. That was when I bought the 10 tubes on sale at 50% off.
