Tungsten is already back!
Look for Tungsten Halogen - all the warm goodness of a white-hot filament, coupled with much longer life and a higher efficacy* than those old GLS lamps.
In some cases, Tungsten Halogen is actually more efficacious than LED, as many LED light sources have really poor drive electronics** and optics.
* Light-source "efficiency" (Wi/Wo) is hard to measure and not very useful. The common term is "Efficacy", usually measured as: (Useful lumens out) / (Watts put in).
For some reason very few of the energy-efficient light source manufacturers make these figures available.
- Do not believe the name-plate rating on an LED fitting, that's almost always the rating of the diode(s) used and not the power consumed by the entire lamp.
** The PSUs in a lot of domestic (and industrial!) LED lights are very poor - some actually dissipate double the diode power.
Even the good ones draw a lot more current than the rating might suggest, as it's drawn in 'bursts' rather than continuously like resistive loads.
- Household supplies must be getting rather nasty with harmonics these days as almost everything uses a switch-mode PSU. Excluding the oven, I've only got about 250W of resistive load in my house these days. Less than my computer alone...
