This post is old, but I’ll add a note: This technology uses an electronic switching supply similar to the one used in a CFL, but at much higher voltage. This is used to generate the “spray of electrons”. Think of the ESL bulb as a CRT without te phosphors seperated into RGB pixels. There are no deflection circuits, focusing, etc. Just a vacuum tube with a cathode and anode where the anode is covered with a phosphor. This means any color can be achieved. No, Mr. Harrison, they can’t be used in an oven or anywhere the electronics would be damaged.

Is this high temperature heat tolerant for use as a conventional oven interior light?

Are this bulbs with E14 heads already in production ? I use 30 w e14 220 v ac spotbulbs from philips, but this would be a very good alternative, when they have the same or better quality in warm light, with the same or more lumen ;)
