I'm considering going back to MH's on my display. The LEDs worked well but there just seemed to be that little extra missing. I currently have a 250 lumatek e-ballast so I'm just looking at reflectors. What would be the best option:
Hamilton Bali sun single ended mogul reflector with a radium 20k
Hamilton cayman sun with 14k phoenix
I like the Cayman sun more. It seems to have more reflectivity than the Bali sun. However, the Cayman sun is only in DE. I've always ran DE and Phoenix 14ks, but I've heard such incredible things about the radium that I want to try it.
With an 18×18" surface area is it safe to assume that any difference in reflectivity between the two is negligible?
