Something like this but I think bulb says 1200W.Link?
Are you doing this for red light or IR? It's going to give you essentially no red light, and the majority of the IR will not be near IR.
All these things work by thermal radiation, so the what matters is the temperature at which they operate. According to some similar manufacturers these halogen heaters have peak wavelengths around 2-8um (2000-8000nm), so they operate at lower temperatures and will put out little red light.

Your graph is for halogen bulbs designed for lighting, and I think even 4100K is too high of an estimate.
Well it certainly looks to put out quite bright red light, the heat is such that 2ft is about the closest usable distance. Are you saying that this heat is not InfraRed?Let me put it this way. You'll get more red light from an ordinary clear 60W bulb.

Just looking again at the graph above I had been assuming that my light was close to the "Halogen 4100k" line but I assume you are thinking that what I have is closer to the "Heat Lamp 2400k" line.
Bulb does not have a colour temperature written on it so all I have to work with is the bright red/orange colour of the light. Could I get a more appropriate bulb to use in this light?
