Things have changed so much since I tried those stick on square boards and now it's hard to remember what I have used in my conversion. The 18" Thinlines and the 12" Thinline tubes and balasts were removed and I used 5, 15" strips in the 18" fixtures and I don't remember the size in the 12" but there are 5 strips in there too. I used aluminum backed strips from Ebay, they come 10 to a set and they are fantastic when glued to the fixture housing. I soldered mine in series with a switch to change from 2 to five strips depending how much light I wanted.
I bought 6 spot lights at "Q" last year and they have two problems that we see. The spot is ringed with yellow and for some reason all of them seem to flicker when the base warms up. The incandescent's are #1383 BA15s bulbs.
Our bedroom is like a dungeon to me, very little light, two small fixtures with two bulbs each. I could replace with corncobs but strips are more efficient in delivering light downward as nothing goes up and reflects down. I'll probably buy to Thinlines when I find them in a salvage yard and convert to the aluminum backed strips.
The only fixtures that will continue with incandescent's are the two makeup fixtures in the bath. I hate them but the DW says it's not worth the money to replace the fixtures.
Now to do the outside.
