How to get at the bulbs?

[MikeandAnne]

Hi,
I have a Fleetwood 640Est, I am considering replacing all my interior bulbs for low power consumption LED types, to reduce my consumption when on 12 volt and off 240 volt hook-up.

I can see the G4 type halogen bulbs in the switched ceiling lights, but can’t see how to get at them. The three chrome studs protruding through the glass covers seem not to unscrew.

How can I get access to the bulbs or am I just not using enough brute force?

Thanks Mike.

We have done exactly that. The studs will undo, try tightening slightly before loosening to unstick them.

The festoon bulbs are 5 watt each and there's 2 bulbs either side, so your running a massive 20 watt when you switch these on, and as you say for very little return in terms of light output.

The diffuser is just clipped in, it's just a matter of carefully praising the cover off at one end, with a pen knife blade or similar, until you can get your finger under to remove.

Your best option in terms of Lumen output for the replacement LED festoon bulbs is to select the highest value available, but don't expect to be impressed with the resulting light output as by the time it has permeated through the diffuser the majority of its light output has been dissipated. They of course consume less power than the original bulbs.

What I've done with my fitting is to install LED strip lighting inside the fitting itself, all I can say is it works, it's more cost effective than LED festoon bulbs and it consumes significantly less power than the original incandescent bulbs.
