I have several 500W cyc wash floods that have a gel holder, and have never had trouble with the gel melting. I'm guessing you are refering to the el cheapo $15 floods that you get from Bunnings? Not sure what the answer is for those. Wasn't this asked recently?

Rosco Colorine is a product which proffesionals use.

Both Rosco and Lee make hi-temp gels which will hopefully do the job.

If not then you could go with an appropriately coloured dichroic glass but it will probably cost you more than the buying a set of lights similar to those that Jeff has.

Failing that, I have successfully used the 500w bunnings floods with standard gels by mounting the gel outside the wire grille and cutting it oversize so you don't get open white spill.

I am surprised that it makes any difference to the melting point when you sandwich the gel between glass. Most glass won't absorb much infra-red radiation (compared to a blue gel which absorbs a lot) and sandwiching it only cuts down on airflow which is the primary method of cooling for a gel.

Be aware that the cheapo 'gels' that you can get are often just cellophane which will melt in no time.

And yes Jeff, there does seem to be an echo around here.

Thanks your feed back - yes the lamps are the el cheapo Bunning’s variety but that's not the point - the "fittings" contain the standard oblong type halogen lamp. I am following up on your suggestions - muchus gracias

So long and thanks for all the fish

Thanks the above. We are using a theatre with fully equipped pro rig/ dimmers/ DMX etc.

The idea of using the halogen floods was mine since they are inexpensive and give a good output. I will persevere with the coloured glass concept.

I noted on Channel 9 TV the other day that similar "stick” halogen lamps were sighted in fixtures. I will sound around.

I am going to UK shortly to follow up some leads there. Your contributions greatly appreciated - I will keep you all informed - from an experienced Gaffer of yesteryear – and experimenting - Peter!!
