content: showing off my workbench shortwave infrared heatermy own design , uses 350mm heat lampsthe lamp its running now is an osram 415v 3kw bulb , it consumes 1.3kw on 240vthe bulb has an white aluminium oxide reflector on on the back half of the glass , it does well at keeping the aluminium housing i built cooleven though it consumes 1.3kw it feels hotter than a 1.5kw 240v bulb i tested , i believe its due to the inbuilt reflector, plus it has about 2 to 3x larger amount of tungsteni constructed a full dimming controller box with 10ma rcdit heats my midsection all the way up to my neck , usually have to dim it down after a short whilealso use it to dry off metal parts after machiningmakes it fun to work on stuff when its freezing cold

content: standing so close to this bulb makes this the most efficient heater there is lolmy chest is about 50cm away from the bulb , its the nicest type of heat

content: if anyone is going to do a build with heat lamps make sure you buy the ones with wire leads , the ones that uses electrical contacts that also secure the bulb in place are prone to failure , at least in the larger wattage heat lampsi tried out one of those bulbs that has a gold/ruby coating over 100% of the glass to reduce visible light but not infrared , it puts out a lot of red light and you can almost look directly at the lamp when on, i dont think ill buy this type again thoughnext i want to buy one that has a 50% gold reflector , i would have already bought one but the minimum order is 10 or somethingseems a waste to throw out the gold at the end of its 5000 hour life thoughit would be cool if you could cheaply get a 300x400mm stainless sheet with real gold coating on one side for a reflector insert , then i could just buy the standard lamps

content: Quote from: daniel444 on March 05, 2019, 11:26:47 amhow about gold plating one yourself?you can watch cody's lab video about electro plating metals with gold. It uses a small amount of gold so it won't cost that much either. you just need the right holder, sand off the paint, make sure the metal surface is clean (you can treat it with HCL as well) and then proceed to plating it.

content: That is a nicely build projectI myself don't have a need for it (yet), since my overhead lamp I use for illumination of my desk provides so much heat that I mostly have six of the eight 80W T5 High Output tubes disabled. But soon I want to rebuild the lamp using LED strips, so maybe I will have a need for a heater like that

content: Also try a heater under the bench, at your feet. Keeps your feet warm and the warm air then flows up your whole body. It's almost a religious experience!

content: here is the first heat lamp i bought , i have replaced the lamp itself, the lamp holder , reflector insert , connector box , and mounted it to a speaker standonly the black cast aluminum housing remains , it was only 40$ delivered in Australia to buy it , it had a flat glass front panel that blocked 50% of the heatthe lamp i replaced it with has a secondary glass layer built in for safety, apparently falling glass fragments could start a house fire

content: This is one project I would go whole hog on. Namely buy one of these:https://www.aliexpress.com/item/pig-rotisserie-motor-Heavy-Duty-80kg-load-Stainless-Steel-pig-Spit-roast-rotisserie-motor/914780261.htmlAttach the motor to a rotating barstool, for an all even bake. By synchronizing your thoughts and actions to the rotational frequency you can be afforded quiet periods of reflection interspersed with feverish bursts of competent action.
