I’ve read through quie a few threads this morning on this topic. I’m unclear on a couple of points.
“They” say 3W/SQ FT. I don’t know if that’s to get “great light” or just “ok light”. If just ok, I’d assume I should plan for a little more.
“They” say that the T8 lighting is brighter than older flourescents. Does that mean I can stick with 3W and be happier, or should I still plan for more?
Home Depot’s web site, just for example, has a fixture labeled as 32W, yet it also states it has (2) 32W bulbs. Isn’t that 64W? And their 32W, 4-bulb light should actually be 128W, right?
I tried using GE’s site to help plan, but it needed too many variables. How do I know how many candlefeet? I don’t think I have one of those! ;)
Currently, my 23’ x 22’ barn with a loft at about 9 feet it by 6 flourescent screw in bulbs (not sure wattage) and a couple of hanging 4’ units. I don’t have enough light. It’s much better with the hanging units on, but I’d like to remove them and the other fixtures to install a grid of fixed T8 units.
I’m hoping this is not too expensive.
So … can anyone help me figure out 2-bulb or 4-bulb, how many units, how many total watts and any insight into the candle-watt specs?
Oh, and HD’s site says nothing about the temperature of the bulbs, so I have no idea if they are 5000K as everyone’s suggesting I use.
