showing off my workbench shortwave infrared heater my own design , uses 350mm heat lamps the lamp its running now is an osram 415v 3kw bulb , it consumes 1.3kw on 240v the 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 cool even 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 tungsten i constructed a full dimming controller box with 10ma rcd it heats my midsection all the way up to my neck , usually have to dim it down after a short while also use it to dry off metal parts after machining makes it fun to work on stuff when its freezing cold |

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

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 lamps i 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 though next i want to buy one that has a 50% gold reflector , i would have already bought one but the minimum order is 10 or something seems a waste to throw out the gold at the end of its 5000 hour life though it 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 |
