Thanks for the link, I hadn't seen those yet. Once they came out with the daylight spectrum, I began switching over to LED in earnest. 90% of the house done and 100% of the interior of the RV. The big holdout in the house is that I can only find 90w equivalent in standard bulb size and I like my reading lights brighter. So I've still got a few 150w spaghetti bulbs.
