Lighting Costs- MUST READ

This is a really cool link. It shows ALOT of info on various aspects of indoor light (i.e. cost per month to run, lumens etc)
You can put in how many hours you plan on running you lights and get an approx. cost.

TOTALLY COOL!

Nice Find Celticman everybody is always trippen about how much it cost to run lights

Thanks!

one thing that REALLY suprised me was which HPS light was actually the most effiecient... It was the 600 watt! I would have thought the bigger the more efficient.
The 250watt was 86 LUMENS per WATT
400 was 96 LUMENS per WATT
600 was 121 LUMENS per WATT
1000 was 114 LUMENS per WATT

For a new project, I was trying to decide between 1-1000 watt or 2-400 watt but I think 2-600 watt will be the way to go.... IF I can come up with the cash

yeah i jsut switched from a 1000w to a 600 digital. So far so good....

How many plants if you don't mind me askin'?

The 600 is more effecient, but did you look at bulb cost? The 600 is the most expensive.

yeah but that was over a five year period.
Plus what I am after is the most bang for my watt.
I don't want my electricity bill any higher than necessary.
