Greg:
I wouldn't recommend globe lamps or any other enclosed vertically aligned batten style of light for that matter.
With the bulb's metal parts just above the bulb and its wiring terminations just above its metal parts, there's a clear fast track for heat to be channeled up towards the wires.
The wires of one globe light that I replaced had become completely brittle. It was a real eye-opener to the problems of heat damage as all the other cable in the property (that I encountered) retained good flexibility. The terminations in the globe lamp had been sound and as the insulation was uniformly affected within the fitting and with the condition of the neutral wire being worse than the line, it seems a straightforward case of heat damage (from the heat given off from whichever bulb the owners may have placed in the 60w, I guess, fitting) to low quality cable.
In this case the light was being replaced by a disk shaped light which, despite its use of incandescent bulbs, the bulbs were at least aligned horizontally to limit the potential for heat damage to new wires.
Personally I'd prefer to use LED and fluorescent fittings that cant accommodate incandescents but would like clients to be able to get replacement bulbs in the future. Any ideas?
