Halogens are about 85% heaters.
For 3D printers, use a 240V bulb, run it at 1/4 power with 120V (P~I^2R) so it doesn't burn out with on-off cycling - by running it only at a fraction of its rated power.
Use a holder - 4.69 or 4-11/16" holder, for a 240V T3 bulb. [5]
R7S is the style of holder -[6]
This bulb is T3 R7S, 118 mm long - [7]
