they suck. XM 10 and 20k's are great bulbs, the 15k's no...

i have the 250W DE XM 15K HQI and i love them. They are a perfect crisp white with a hint of blue. i have all sps and lps and they look awesome. Also i didn't use atinics for about 5 months and they still looked great, but an atinic supplement is still a good idea.

They are not good bulbs. The par readings came out to be below an XM 20k bulb which means that the 20k bulb is more likely to grow coral faster than the 15k. I tried it myself about 2 years ago and all it gave me was super slow growth and algae.
