The last time I was in the lighting area of our local Menards (think home depot), there was not much choice in any LED lighting. You could but the light and fixture (didn't say "replaceable lamps" or not), but those fixtures were all odd sized (44" instead of 48" or 32" instead of 36"). There were no 48" nor any 36" LED lamps in the store. There was almost no choice in any replacement LED lamps only. For that matter, there wasn't a lot of choices for Fluorescence bulbs in any size in stock either.

Tends to make one wonder if maybe replacement bulbs for anything may be a thing of the past. It may also indicate that maybe if your thinking that you want to have replacement bulbs available when what ever you now have, you better plan one storing them for yourself.
