We have one of those naff gas fires that has the yucky moulded pretend
coals that are illuminated by a couple of red bulbs driving spinners - the
"flicker" effect - by convection. Yes, the fire will ultimately be
consigned to oblivion, but not just yet.
The other day I realised that the two tinted bulbs, at 40w each, are using
more juice than is used illuminating the whole of the room (done entirely
with CFLs - 6 in total, although unimportant to the question following).
By way of experiment, I fitted a couple of CFL lamps in place of the tinted
tungstens to see if they generate enough heat to spin the flickerators and,
although they are a little slow to start, it does work, which is good
enough for me.
Not good enough for SWMBO, of course, because the rosy red glow is now
beaming, cheery yellow.
OK, to the point, unless there's a compelling reason not to, I need to red
lacquer the CFL lamps so that the illusion of warmth is imparted to the
room, and so that, in spite of the CH turning the lounge into a sleep zone
for me, the Mrs doesn't feel cold.
So, and sorry for the long tale, what I'm looking for is a suitable lacquer
to use on the CFL lamps. Any suggestions re. type & source?

Try a transparent modelling lacquer (from a modelling shop). I've used that
on smaller bulbs before.

The other option might be some stage-light colour film which is good to high
temperatures (much higher than a CFL) - wrap around the bulb and tape in
position.

Cheers

Thanks Tim, the modelling shop I'll follow up.
I had already decided that enclosing the bulb in a gel filter would
interfere with the convection.

Nail varnish? Choose one she likes most ;-)

6 packs of little pies usually come in red trays - or did last time I
bought one - and these make effective light filters. You may find red
plastic sheets in your local art shop, though I daren't ask at what
price. They'll be the cheap low temp version of lighting gel.

Yes, I know the ones you mean, thanks, but I think they will divert/block
the convection currents.

I was thinking theyre large enough to be put where they wont.

Lacking the heat of convection, I suppose the modern way would be to
drive them via a synchronous small clock motor. As this is a
modification and has to work with a flow of air - how about a small
mains powered computer fan to supply the essential flow of air?

Sorry, I was stuck thinking in terms of enveloping the lamps. :-)

I think those small fans work on 5V or 12V at the most.
Perhaps a sterling engine design might work.

Do you have the bulbs on when the gas isn't? If not, I can't see why
you want to remove 80W of heat when you're spending so much on the
1000W (say) heat from the gas.

Good question - in practice, and other than chilly summer evenings, the gas
is never lit, as the room is heated by the CH rads. It's all about the
perception of a "warm" room. ;-)

nail varnish.

Right, implemented this yesterday, and it works well enough.
Convection is lower than the incandescents, so a bit slow to initially move
the spinners [1], but perfectly tolerable, and SWMBO has announced that it
qualifies as a satisfactory solution.
Thanks for all the suggestions - the Owl meter has dropped a couple of
points, so honour is satisfied. :-)

[1] Will try bending these to different pitches, but that can be done at
leisure.
