Not sure if the ballast was to blame or not. If you look at the chart here, cnidarianreef.com/lamps.cfm you will see that with a lot of bulbs, the Coralvue ballast provides higher PAR and wattage with less amp draw. Take the XM 10k on the CV ballast. PAR of 541 with 257w. On the Icecap ballast it drops a bit to 530/252. Difference in draw is minimal at .01a less with the CV ballast. Other ballast show similar results, I was just using the Icacap as an example because it's pretty well used. I can also say that the CV ballasts run much cooler than others I've used. I don't have any comparison numbers but the CV wins the "touch" test
