Joe,
I bought some 20k, 250, SE bulbs from them. Price is great. I thought they were a little too white to be a 20k... for my liking. Also, one bulb looked a little different in color from the other. I did not really give them too much time on my tank to comment on growth. I still have them if you are after that type of a bulb. I ran them for like 2 weeks. Send me a PM.
