275w photo lamps have very very short lives though, they're meant to spend nearly all their time run 2 in series, and just get 240v for the brief moment of taking the photo.
I stockpiled some incandescents too. Not had a single use for one since.

How small do you think an micro "environmental chamber" could be and still be useful?
150mm cube inside? 200 x 150 x 150? (8" x 6" x 6"?)--sp
I just ordered one of these:

which is 5x5x7.5 inside; maybe kinda small? That might do for a lot of my needs, like curing epoxy or temperature cycling small gear or breadboards. We can keep it in the common lab and anyone can take it to their bench as needed. We have a giant chamber in the basement (goes to -70C!) but it's a big deal to use. Something like 0 to 50C is plenty to estimate tempcos.

Mo has a mini-fridge in her office. Sometimes a big guy will bring in his kid for therapy, and she sits the dad on a couch and gives him the wifi password and a cold beer.

It arrived today. Pretty neat. It has a switch for hot/cold. Cold is
7C, hot is 51. It's about the right size for a small breadboard or even a small product. You could put a thermocouple on the DUT, switch from hot to cold, and in maybe half an hour do a temperature sweep.Looks ideal for curing epoxy. Looks like TEC for cooling, resistive heating.
A little bigger would be good too.
$40, including shipping in two days. Amazing.

How about a coffee/tea mug warmer?

Have you looked into UV curable stuff? I have some and it works well.

I use one as a one-sun (OK, it falls short of sunlight), for testing battery-charging with small solar-panels.

Nice. Where'd you get it John? Or did you make it yourself?
Thanks,

I like the cute little cold/hot mini-fridge. It cost $40, but it will keep a few beers cold too. Sometimes cold is useful.
