Thinking about giving these a try...

150 Watt 20000K Metal Halide Bulb - Radium, Double Ended



Has anyone tried these bulbs?? It's getting time to change out my 14k bulbs and I am looking to try something a little differnet. I have heard the 20k bulbs tend to be on the dim side, but these sound like they are on the brighter side... I do not have access to anywhere I could preview these bulbs, so I will just have to go on recomendations.



Any feedback would be great ;D

 

i havent tried them only because i didn't think they made them in 20k, if you try em let everyone know how they work out

 

Lot of people like the Radiums, they burn really blue.

 

I purchased a 150 radium DE for my GHA test tank, so far I love it ;D

Color is noticeably more blue compared to a SPS 14k, but it is not obnoxiously blue. Bulb is very bright, much brighter than 20k bulbs that I have used in years past (note... last 20k bulb I used was well over 10 years ago).

I tossed a few corals in the test tank and I will be watching to see how they respond. Will also be curious to see if there is any affect on GHA growth.

Going to run it for a few months, and if things continue to look good I will pick up a few more for my other tanks.
