I had the same problem with the same bulbs. I emailed them and they took it back

I just called J&L and they said someone would call me back. I'll take a picture so that you can see the difference when I get home tonight. I did raise the lights quite a bit so I guess I will wait a few days and see what happens. If I end up sending the bulbs back then what would you recommend that I buy instead?

I also had that same problem. I bought mine from a LFS here in Calgary and exchanged it for a 20K bulb. Maybe a bit too blue but much better than yellow.

I have read on this forum that a halides spectrum can change rather significantly during the "break in period".

I know this holds true to security light metal halides lamps!

Another way to acclimate your new bulbs and your livestock, is to raise your lights and put a layer of black fibreglass window screen over the top of the tank. It lowers the intensity very nicely
