Lighting - WPG

[charlie]

All-glass aquarium has available an efficient 10 watt mini compact replacement bulb for the small aquarium. This bulb features more natural aquarium lighting and easily screws into many aquarium hoods and strip- lights. This bulb provides 6500 k light that promotes live aquatic plant growth for your fresh and saltwater aquariums. Mini compact bulbs also feature the equivalent light output of 50 watts of light. Longer 6000 hour life replaces 6 incandescent bulbs and the mini compact uses less energy to operate. All-glass mini compact aquarium bulbs are c ul us listed and operate on 110 - 130 vac.




So which rating do you use to calculate your WPG Watts per Gln The 10 watts or the light output of 50 watts.
Regards

10 watts..  the 50W is mostly heat generated

To be honest this question is not so simple to me
I would say "Lumens" is waht should be counted.
"WPG" - is not a reliable way. You should check he intensity of light.
According to the info I found, this parameter has the greatest impact (optimal wavelength can give you just 10% additional).

i just paid 25$ for a 10w for  my 10g...its so expensive!!

...and I just paid $220 for a used 192 watt fixture...and I consider that a great deal for the quality of light I got   (Thanks LowKey :wink: }

whia, thats a lot of watts, its it for you big aquarium?

really?  incandescent or florescent?

If its the heat machines, the single tube kind, you just got ripped off!!

I think walmart sells 2 for $1.99 or something like that.

I'd cough out the $12 and buy those spiral-light (and reseal the rim with glue)

It's one of the lights I'm putting over the 120,  The other has two 55 watt bulbs, so I will have a total of 302 watts giving me 2.5 wpg which should be sufficient for decent plant growth.

... and living room lighting!!

I am still in love with that tank setup!

Dan, you're compliments are greatly appreciated.  Can't wait until you patent and market your tank "automation" system.  I'll buy the first :wink:

Then you got the Actinic, pretty much useless for growing plants.

I get all my flourescents from Home Depot or Canadian Tire or the like. "Daylight" is usually a good range of Kelvin for plants, and you're not paying "premium" for so-called specialised aquarium lights!

useless?? wooo buddy....2 weeks i have all my plants, 2nd time i have to trim them...LOL the guy told me it was the best for plants...

Different people, different plants, different luck...

Lol, sounds like a plan.

I'm actually re-doing my entire setup!  I need to buy new pipes and I need to invest in new hardware....oh well, 2-3 years left of school!! plenty of time!!   (mine are all shot....forgot to turn them off when changing water lines...)

Here's an example of the pumps I use:

I may not use this exact one, but the idea sticks.  The ones I normally use can shoot upto a head of 15'  (in feet), so a closed loop or 3' incline at 50' of tubing is OKAY.  I use three of these, two into the tank, one to remove from the tank.  It's too bad they are loud, but atleast they only need to pump for a few moments at a time (longer then 15 seconds a shot can shoot out the motor I believe).

forgot to mention, these pumps can hide in a basement or such, they are pressure driven (*may* need priming if its a long hose...).
