It's a Marine Corps thing. Or used to be before the invention of the stress card
I recently built a can heater to regulate the temperature in my fermentation chamber on cold days. The can heater uses a 60 Watt incandescent light bulb as a heat source. As of Jan 1 60 Watt bulbs can no longer be manufactured in or imported into the USA. Any suggestions for alternatives? Many of the new efficient bulbs produce far less waste heat. The 60 Watt bulbs will probably be around for a while. Maybe I can replace with a heat lamp? Just wondering what people think.
