View Full Version : USHIO bulb question

06/22/2006, 06:31 PM
Anyone every used the USHIO Euroflood 10000k DE bulb on their tank? I ordered what I thought was going to be a USHIO Aqualite 10000k DE bulb online and got the Euroflood instead. Will it even fire in my BlueWave III ballast? What about color difference?

The only differance I see on the bulbs specs are:
Excellent color rendering — 90 CRI for the Aqualite
Excellent color rendering — 80 CRI for the Euroflood

Anyone what CRI means and what differance that would make on a reef aquarium?
