Stupid lighting question

[gomrjoe]

A buddy of mine and I are having a debate, a stupid one admitidly, about PC lighting and how the wattage is advertised, and what it really is!!

When they say a Dual PC bulb 2-65 Watt daylight, is that 65 watts per individual bulb? So in the case of a dual, that would mean that each individual bulb is 65 watts, and together (because they are side by side) they total 130 watts? Or is the whole thing (both bulbs of a dual) total 65 watts?

I am confused now. I believe that each individual bulb is 65 watts, and total output for a dual is 130?

What does everyone have to say about this? THanks,

If there's two 65w bulbs, then it's a total of 130w. Just like if there's two 250w MH bulbs over a tank, it's 500w and so on...

wait are you talking about two bulbs, seperate, with two sets of pins, or are you talking about the two tubes in a single pc bulb?

Ea set of 4 pins = 65W (it looks like 2 tubes per set of 4 pins, but they're connected at the far end via skinny, but hollow glass tube).

Yes, the wattage quoted on power compacts is total for the bulb..not each tube..

thanks for the clarification. It seemed like that made the most sense.

Thanks.
