Comparing PAR readings

Before I went with my CV lumerbright/12k/CV ballast combo, I was seriously looking at running the Iwasaki over my cube but the back order & cost of the bulb turned me off somewhat.

I think it looks nicer than the Radium look and wayyyyyyyyyy nicer than the 10k look, although I,m sure it was loaded with par.

Yeah, I really love how the Iwasakis look with the actinics. It's a perfect balance especially considering the electricy vs. PAR ratio. The XMs on the HQI were extremely powerful but a little too yellow and the Radium blue got a bit tedious after a bit - while reds, greens and blues really popped, the Radium washed out yellows. The Iwasaki is juuuust right - it is absolutely perfect with the actinics.

I got the Iwasaki from Marine Depot in the US and had them sent to my PO box in Pt. Roberts. They are much cheaper this way especially with the better Canadian dollar nowadays.
