$700 for a $7 lamp?

I may have missed this part of your health regimen… why red light chicken heat lamp instead of just morning and evening sun + “blue blockers” (or just no devices after a certain time)?

Have used it, I like it a lot. But it was a friends, and no I didn’t like it enough to spend $700 on it myself. WTF??? Why is this not $79 plus shipping!???
