We have some mini garden lighting. It consists of 4 lights. Each light
runs off 12 volts and is rated at either 20 or 30 watts.

We would like to change the colour of the lights. We have tried using
filters fitted around the bulbs but these just don't seem to work.

Is there any paint that is designed for use at high temperatures? We
were thinking of spraying the bulbs or the glass surroud that goes
over the bulbs.

I realise that the paint might insultate some of the heat and reduce
the life of the bulbs but this is something that we can live with.

Any suggestions for a type of paint that is designed to work with
higher temperatures?

Thanks,
Graham

If they are MR16's, they are available in coloured versions.

I don't think this would work with bare halogen capsules, if that's
what you're using. They run at around 350C.

Ideal question for a theatre lighting group such as
rec.arts.theatre.stagecraft who will be familiar with
the current state of the art of high temperature filters.

Bulb painting can be done with the paints from stained glass kits, also
yellow headlamp paint. CFLs are low temp enough to be painted with
anything seethrough.

But if youve got bare halogen capsules, forget painting them, or
putting anything close, they run at very high temps.

Theater gels are also available, but are steeply priced considering the
other options.

Forgot to mention, some other no cost filters:
red flexible plastic trays that cakelets come in, eg kiplings etc
green plastic 2l bottles, use 2 or 3 layers.
bottles of other colors
sweet wrappers for tiny lights

But none of thee are fireproof, so must be fixed with due caution.

As a resident of rec.arts.theatre.stagecraft I can tell you that the 
best way would be to buy coloured MR16 lamps. Maplin sell them, amongst 
others.

Theatre colour filter would work, but even the latest high temp stuff 
fades over time and needs replacing. The coloured lamps use dichroic 
filter which lasts for ever. If you want to pursue the theatre colour 
filter idea, your local disco shop will probably sell you some.
