Let there be light!

As an FYI to all you mathemeticians here.. ;) :D

Actinics really don't provide the lighting that a regular lamp or bulb creates. I'd hazard a guess to say that the Actinics most here in this thread are adding into their wattage totals aren't really a good indication of how much light energy you are putting into your tanks. Anyways to sit and compare the wattage of a MH to the wattage of a VHO or PC is like comparing apples to oranges. Watts per gallon as well isn't that good of an indication of light energy going into a tank. Jamie is running 2x250W HQI's which kick 2x250W Iwaskai's butt from here to the north pole.

I just measured the lumen output of three 95W VHO Actinics and it barely put out 3000 lumens at 4". As well the PAR of those three is only 100. Not a lot is it.

They put out energy yeah.. but in only one wavelength which means you are putting a whole lot less energy out than an identical lamp having a kelvin temp of say 10KK.

With that said.

16.2:1 :D :D Beat ya Titus..

You're fourth now Mason.. :D :D
