When I had the big building, I put up 30 of these: I didn't get them all at one time. Just when there was a dark spot and I happened to get by Home Depot, well, you know how it is. I know I have 30 of them because this morning I dug them out and sorted through them.
Had 27 watt (100 watt equivalent) CFL's in them in the daylight lumen range. Made things nice and bright.
A couple of weeks ago I saw this in Woodworkers Journal emagazine:
That gave me an idea. I won't use the same materials, just the concept.
Let's see, I had 30 in a 24' x 36' building. Now I have an 8' x 24' trailer, 1/4 of the space. Wonder how many I should make? What what I should do with the left overs? LOL!
