Comments: Bulb replaced a SPS 14k in a 50g test tank. It is distinctly bluer, but not obnoxiously blue. Much brighter than I expected compared to 20k bulbs I have used in the past. It has only been in place for a few weeks now, so I cannot comment on coral health/growth effects long term. So far I love the look and I think it will be a good change. Yes, I would recommend this product to my friends.

Comments: Added this to my JBJ 28 from the stock 14K MH. It gives off a great color not to blue and makes all the corals colors pop! My clam is loving it also. Worth the price! Yes, I would recommend this product to my friends.

Comments: I purchased three Radium 150 watt 20K double ended bulbs. They are excellent bulbs and really make the colors in my 210g reef tank really look great. Although the price is high I would highly recommend these bulbs. I will purchase radium bulbs again when it is time to replace these. Yes, I would recommend this product to my friends.

Expected a bit more by Tom L.

Comments: This bulb compared to my JBJ 14k is almost exactly the same brightness and intensity, but also added a little actinic pop to my corals. I still had to install some pc actinic lights to get full color out of my corals. I should have kept my 14k and added the pc actinics as it seems to be the best combo. The 150w 20k bulb is nice, none the less. It's just not a replacement to true actinics like the 250 w bulbs. I would not recommend this product to my friends.

Outstanding Bulb by Saxamo!

Comments: I have been using this type of bulb with great results for a couple years now. I find it to be the best bulb on the market to date as a 20k or Bleu. Crisp white colors and the spectrum my corals want and need. I suggest for anyone out there running a reef tank to give these a try. I am sure you will be like WOW, that's what my tank is suppose to look like! Always remember to install with dimple up. You will really appreciate this bulb! Kind regards, Saxamo Yes, I would recommend this product to my friends.

Comments: I bought the Radium and have it side by side with a Phoenix 14000K. I can not tell the difference in overall color but the radium side coral have more actinic POP to them over the Phoenix side. Especially the green colored corals. Yes, I would recommend this product to my friends.

Comments: Perfect! Nothing else needs to be said! For a 20,000k bulb it is VERY bright!! It doesn't have an overpowering blue tint either. It is the perfect blend of actinic and white lighting. I highly recommend this to anyone that doesn't have room for supplemental lighting. Yes, I would recommend this product to my friends.

Comments: Received it and hooked it up about a week ago. I was ecstatic to find Radium finally makes DE bulbs! If you're considering this bulb as a 20000K, it's worth every penny. I'm buying another for my 250 watt ballast! Yes, I would recommend this product to my friends.

Radium 150K DE Bulb by CHRISTOPHER PELUSO

Experience Level: Intermediate

Posted on 6/3/2008 from SCOTTSDALE, AZ UNITED STATES

Comments: I was thrilled with the light produced by this wonderful bulb! I have a 24g tank with only a single metal halide fixture and no possibility of adding actinics. I experimented with several different bulbs - brands and wattages, but my coral colors just wouldn't "pop." Finally, with the Radium 20K, they "pop" just as if they were under actinics. My research also showed that the 20K Radium has more PAR value than any of the other 14K or 20K bulbs. It is blue, but very bright. Yes, I would recommend this product to my friends.

Comments: I haven't tried alot of different bulbs, so my comparison is minimal. I've tried the phoenix 14k, and one other 20k bulb (I forgot the name). So far this is the best. Yes, I would recommend this product to my friends.

The best 150 watt 20K bulb by GREG CARROLL

Experience Level: Expert

Posted on 8/29/2007 from MIRA LOMA, CA UNITED STATES

Comments: All I can say is "Wow!" The color on this bulb is fantastic. Running on an HQI ballast, this bulb burns a crisp blue/white with just enough actinic pop to run this bulb without supplemental lighting. It is suprisingly bright for a 20K which was a pleasant suprise because most 150 watt 20K bulbs are quite dim. Yes, I would recommend this product to my friends.
