If you mean the 50,000K DE bulb instead of 20,000K then the bulb is very good. The color is great but the growth isn't what it should or could be.

It depends totally on what your looking for my friend. If you want coral growth, the fact is the farther away from 6500 the slower your growth will be. I chose to go the middle of the road and get a 14k Phoenix. They have great PAR for a higher kelvin bulb and they look freggin sweet. I am not willing to take the huge hit on growth with the 20k+ bulbs.

I have heard good things about Iwasaki 50k, but this 20k de from Iwasaki just came out. I think I may try it. Check out under light bulbs on this site.
