Lights64 - HQI 150w MH - PlusRite

[Matt]

Has it been another year already? Time to replace the bulbs... Last year, I replaced the stock 10000K Coralife bulb with a 10000K Ushio. I didn't notice a substantial difference in the quality of the light, and the reef motored along without noticably changing in response.

So, in my opinion, with a test sample size of 1:
Coralife = Ushio

This year, I've replaced the Ushio with a 14000K PlusRite bulb purchased from Lights64 on ebay. I've left it to break in for a few days. It is noticably brighter and whiter than the Ushio at 1 year. Shimmer is more pronounced (good or bad - I don't know, but it looks nice). Coral colour and fish colour are better. Much of this can be attributed to the higher K, although it hasn't shifted to blue at all, just less yellow.

Very nice. Very affordable. Easy to recommend.
