I appreciate the info guys! Definitely looking more into the bulb outputs now, and the idea of getting to use my old fixtures is tempting. Sorry about the 21 questions, but what is your opinion on cleaning the reflectors instead of replacing?
I have some old adjust-a-wing style lights that are about 2 years running, 2 owners, and the last crop was a bit hairy. I'm thinking it was because of poor light quality. Either the bulb (which is more likely imo), or it was the reflector (also a good possibility cuz it had some one-off cleaning streaks). I heard that if you clean the reflectors with alcohol, then clean it with a new rag of ro water and 3% vinegar you wouldn't get those "calcium streaks".
