I am currently running Coralife 4 x 65Watts(48" fixture) bulbs over my 90 gallons tank. Recently I have been reading around on the forum that light intensity is also a important factor. Are there better PC bulbs out there on the market that would fit my Coralife light fixture and have better intensity? DO I always have to stick with coralife PC bulbs for replacement? I have the straight pin bulbs at 65watts and 23 inches long.

Many people like the GE 55w 9325K straight pin PC's for plant growth and great color. Here's three places that sell them:

Coralife has a 65w straight pin PC that is a Colormax/6700K bulb. http://www.bigalsonline.com/BigAlsU...coralifecolormax6700k65wpowercompactlampstpin

Current has a 65w straight pin PC that is a 6700K/10,000K bulb. It's item # CD-21119: http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=13314&N=2004+113346

Two of the 9325K bulbs with two of the 6700K/10,000K bulbs would work well. Also, two of the Colormax/6700K bulbs with two of the 6700K/10,000K bulbs would work well.
