Glad to see that PC lighting is makeing a strong showing.........my system is currently using 2x65 watt CSL smartlites..2x65 watt CSL britelites(10000 k)...and 2x40 watt no 03 actinics
soon will replace the 2x40 watt no with 2x110 watt vho 03 actinics
this lighting is doing well on a tank with numerous 'shrooms...polyps....lps coral a few leathers and coraline covering the sides and back
also heat has been a minor problem compared to heat from equal MH systems
