Hands down the best bulb! You will get to see colors in your corals you did not know existed. These bulbs put out quite a bit of par also.

Gotta have 'em! By Bill on 1/3/2011

These bulbs are absolutely amazing! No more cheap 20k bulbs for me! I have a 6' 125 gallon mixed reef and I used to have to run 2 6' VHO Super actinics and 1 6' VHO 454 bulb along with my cheap 20k's to get nice coloration. With two Radiums I get beautiful color with no need to enhance with VHO's! Just the savings on electricity alone justifies the expense, and BRS has the best pricing I've found for these!

These bulbs have great blue color that really make greens, reds, and, blues pop. They are a little pricey but worth the cost. I will use these bulbs again.

I use 2 MH fixtures over 160 tank. These bulbs really make the colors on my corals pop compared to previous 140000 Ushio bulbs. I have now turn off my Atinic T5's when the MH are on and get great color. They start real blue but after burned that settles down.

These are by far the best bulb I have ever used, the growth I get is great and it has just the right amount of blue in it to make corals "pop" with no supplemental lighting. They fire every time on my lumatek dimmable ballasts.
