topsy100 Posted April 12, 2016 Share Posted April 12, 2016 Hi all Has anyone had any success with painting glass in 150w floods if so what did you use? I'm trying to change some floods to 'Blues' to use as wing lights, gel won't work as heat will melt it quickly. No budget so can't install a blue led which is what I would have liked to do Cheers Link to comment Share on other sites More sharing options...
ImagineerTom Posted April 12, 2016 Share Posted April 12, 2016 The heat produced is epic - trying to paint / gel them down using any technology will be a phenomenal waste of time (I'm speaking as someone who's had to convert then trash a lot of halogen floods) - you can buy CFL & LED bulbs that retrofit in to common flood housings; they will be cool enough that you could GEL them down to blue. Failing that complete mains powered 10w LED floods can be purchased on ebay for £10 each including shipping - my honest advice would be to just buy a load of those as the time you will spend trying to convert any existing system will cost far more than that.

Tomo Posted April 12, 2016 Share Posted April 12, 2016 There are only three ways to do this: a) Change the light source to something you can gel. (Theatrical tungsten, LED, CFL etc) b) Change the light source to something natively blue. (LED etc) c) Get blue dichroic glass. (Expensive) Link to comment Share on other sites More sharing options...
david.elsbury Posted April 12, 2016 Share Posted April 12, 2016 Blue CFL would be an option too- a venue here had them in those sealed outdoor bulkhead lights. Link to comment Share on other sites More sharing options...
Dave m Posted April 12, 2016 Share Posted April 12, 2016 150w floods as blues will be very hot and bright.You'd be better off with lower power, and more of them Link to comment Share on other sites More sharing options...
mikelx Posted April 12, 2016 Share Posted April 12, 2016 I have used cheap bulkheads painted blue on inside with paint from Flints and then fitted with 7watt cflAgain low power but quite a few in strategic points around stage. Link to comment Share on other sites More sharing options...
musht Posted April 12, 2016 Share Posted April 12, 2016 No budget so can't install a blue led which is what I would have liked to do Cheers 2 quid each: http://www.ebay.co.uk/itm/2pcs-BLUE-48-5050-SMD-LED-Panel-Light-T10-Festoon-Dome-Adapter-Bulb-Lamp-DC-12V-/281905707425?hash=item41a2e3b9a1:g:qkYAAOSwT~9Wkn-o Not reccomending vendor just type of panel, 5050 for brightness against 3528 or 1210 Wall wart or PSU in the flood housing to taste.

Jivemaster Posted April 12, 2016 Share Posted April 12, 2016 150w floods will get too hot and be far too bright. When dimmed enough there will be so little blue left in the warm glow that blue gel will be functionless. Many other things would be a better starting point, especially LEDs or golf ball tungsten lamps about 15w http://www.lightingever.co.uk/12v-led-strip-light-300-3528-5m-blue.html?gclid=CjwKEAjwubK4BRC1xczKrZyj3mkSJAC6ntgrvV1_s1LjWd2C7pPD3h3-Z5MLXQdQqXM8Kqyc1_6iIRoCcDnw_wcB Just one link from google. May need feeding with low volts. Link to comment Share on other sites More sharing options...
Don Allen Posted April 12, 2016 Share Posted April 12, 2016 The Lightbulb Company in the UK has a Bulb Finder on their web site, selecting Blue gives 54 blue "Bulbs" which would make it easier than painting. Link to comment Share on other sites More sharing options...
