I dont think the same wattage means the same heat.

I dont think the same wattage means the same heat. Compare touching a 25 watt incandescent light or halogen light with a 25 watt power compact lightbulb....

Energy is NOT only heat and light, there is sound, chemical, mechanical etc.
And no when you are talking about light it doesnt mean it has to be about heat, like i said before, touch a 25 watt incandescent bulb that has been on for about an hour. Put on a bandage and use your other hand to touch a 25 watt PC bulb. Which one is hotter? They are both light....

Now why do we use the XM20k lamps at all the shows we do? Because Sanjays lamp reports say that the XM 20K lamp produce the highest PAR using standard M58 and M59 ballasts on his list. These ballasts are the most common in the overall aquarium industry.
