So growth should be OK. And they're blue, so colour for our esthetics should be OK. But really, the only way to tell for sure if you'll like 'em is to try 'em for yourself.
I was absolutely convinced that Iwasaki's were the way for me, based on what I've read over the years. Now that I finally have them ... I must say the one real disappointment I have is they really do not do reds any justice. I see fantastic reds under, say, 250W HQI 10000K and in my tank they're just a wee pink. So... once these Iwasakis are spent, in a year or whenever, I might give the radiums a very serious think. Since that will be an option somewhat affordable (comparatively speaking), because, while the HQI option sure looks nice, I definitely can't afford that unless I came into a lot of wealth (still waiting... :rolleyes: ). The radiums, at least they're mogul so more DIY options available and the bulbs seem only marginally more expensive than, say, Iwasaki. (Someone said $150? My Iwasaki's ran me about $100 each, well, hmm, maybe more like $90 each.)

dont choose that bulb for notting I do intense research
