View Full Version : Blowing bulbs
16th Feb 2012, 12:07 AM
My tenant is complaining that bulbs are always blowing in a couple of wall fittings. They are on a dimmer switch and we lived in the house for 12years and probably replaced 3 -4 bulbs in that time. The tenant is claiming he has blown 4 bulbs in 6 months. He is concerned as he says they are expensive . He is using ones that look like the traditional incandecent glass bulb but have a halogen bulb inside. The fittings are those half oyster shell type - open at the top. He believes the wiring is faulty. he currently has compact fluro bulbs that are working but I warned him not to dim them.
What would cause this sort of halogen globe to blow when the old incandecent didn't?

Loose neutral somewhere in the circuit or paranoia.
Buy him ten globes tell him to call back when he runs out.

Get a close look at one of the bulbs. Does it have a long halogen capsule with a single filament inside? Or a short one with the filament doubled over usually in a "V" or sometimes a "W" shape?
If it's the former and the brand is Philips then that could be the issue. Philips used to make a product known as HalogenA before these lamps became popular and they were incredibly temperamental things prone to early failure. Looking at the newer type bulbs, Philips seem to be using the same "long" halogen capsule whereas other manufacturers have gone for the shorter version with "V" or "W" shaped filament. The Philips one looks to be exactly the same as the troublesome HalogenA lamps had.
