I bought up a bunch of 100 w incandescent for the winter. 3 of them on desk lamps on my model building table warms things up nicely when I am building. Switch to LED in the summer.
Funny that you say that. I was thinking that I may miss the warmth I was getting in the winters.
I have also recently gotten into vintage Aladdin kerosene lamps, however, and have discovered that they put out a tremendous amount of heat, while operating. I use them in the winters. They have to be put away the rest of the year.
