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
daniel444:
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
