I'm using 10,000K bulbs from Greatdel. I've used the 14,00ks that he had as well but wasn't happy with them. I switched to the 10,000k and have seen a marked increase in growth on my corals. When I was using the XMs (I paid $75 plus shipping each) I was very disapointed in the light I was getting and I really didn't notice much coral growth.

I'm on my second set of 10,000K bulbs from ebay now (I change my bulbs every 6-8 months) and I'm very pleased with how my tank looks and the growth I'm getting from my corals.

Scott, your fixture came with Coralife MH bulbs as did mine. I replaced them with cheap eBay bulbs in January (10k). I don't have a meter to check them but the corals I got from Ziggy are doing great under them. I'm considering replacing them at the end of June (6 months) instead of waiting a year like I did with the Coralife's.

My eBay bulbs were like $10.00 vs. $60.00 each for the name brand bulbs. Replacing 3 bulbs every 6 months vs. a year is worth it to me for the $150.00 savings.

Next bonus I may buy a light meter

That's cool. I probably would have stuck with the 14k bulbs if I was happy with them. I tried XM 10k's and didn't like the color so I never really thought about trying them (10k) from Ebay.
After my bad experience with the 1st one blowing out, then Sanjay telling me about their "quality", I figured lighting is pretty important so I'll stick with the more proven bulbs.
Bottom line is you got to stick with what is successful for you.

I got my bulbs in today (and a free t-shirt..lol). 1st impression...WOW! These bulbs are B R I G H T. Here's some pics comparing the bulbs. My camera isn't the greatest, but all the pics were taken with the same settings. All I did was resize them. I took pics of the Hamiltons, turned them off. Put in the Iwasaki's, let them warm up for about 15 mins, then took the pics.

Here is the Hamilton 14K.

That's a pretty big difference. How old are the Hamilton bulbs?
Re-take the photo in a couple of weeks after the new bulbs reached their burn in period (about 100 hours?).

The Hamiltons are exactly 1 yr old. I get replacement bulbs every year for my birthday

Yeah, I'm thinking they may "blue-up" a little more after they break in. They are very white now. I'll take a few more pics in a couple weeks to see if there is much of a change.

Happy Birthday Larry

Mine was the week before.

I'm thinking of heading up to TooFishy after lunch for some 89 base rock, a royal gramma and perhaps a new clam. Though with gas prices approaching $4.00 I keep re-thinking that idea
