ok chris, im going with the walmart lights since you have had such good luck with them, all i hear on here about lowes and HD is bad stuff so im staying away from those. i went today by 2 walmarts in my area and was able to score 2 fixtures at each store so i will keep checking back. what about the bulbs, which ones should i go with? (4100k or 6500k) i dont know what the #s mean but i see alot about different bulbs on here. my shop is 30x30x12 with light grey epoxy floor and white insulated walls and unfinished ceiling, in your opinion how many should i use, how bright are they? and how old are yours, how long you been using them? sorry if i ask to much but all this and yourself have really help me.
Wow, pretty tall order here. I can hit some of this;
I went with a mix of 4100 and 6500 but that was more because I had some leftover 6500 bulbs.
4100 is pretty much your normal fluorescent light. Much like you see in stores everywhere, or in the old R12 bulbs.
The 6500 is the 'daylight' type. I have them in two rooms in my house, and the 4100 in another room. The 4100 looks 'normal' if you are in it. Then walk into the 6500 room near by and it looks blue. Odd looking. The actual light may be better as it is nearer to daylight, they say.
Lots use them for in door plant growing. Possibly legal plants, but I wouldn't know...
If you use to few lights, use the 6500. Otherwise they may not pay for themselves.
If you buy them at HD they are about twice as expensive as 4100, even worse than the bulk 4100 bulbs at Lowe's.
If money was no object I would probably use the 6500s, as there is a little more light there for the wattage.
In my shop I presently have 13 double fixtures, or 26 bulbs. Light gray epoxy floor, white pegboard and silver radiant barrier for walls. That's in a 672 square foot garage, or one bulb per 25 square feet. Most people would say it is too bright. I am thinking of adding another fixture or two, but I am older, my eyesight isn't what it used to be.
I also have a single light (500 watt equivalent) right over my work bench. My eyes are old and that helps.
My oldest lights in this set are only a year old. Most are only 90 days or so as my shop is new. The older ones I moved from the garage to the new shop.
So I can't say how long these fixtures will last. I have seen posts from people using them for three years or more, but I haven't.
You can always assume you will use bulbs faster than you should if you don't heat/cool the shop like you do your house.
I notice the bulbs that are left on last longer by a LOT.
However, I switch mine on and off all the time. If I leave the shop I shut them down. Maybe five-six times a day. They are off at night.
I lost one of 13 of the WalMart units. Just died after a cold night. Of course, WalMart exchanged it no problem but I did lose one. Still better odds than HD or Lowe's units, at 1/4 the price.
