richardc1983 Posted October 30, 2007 Share Posted October 30, 2007 need to use one of these http://www.ukdj.com/index.asp?PageAction=VIEWPROD&ProdID=24273 ://http://www.ukdj.com/index.asp?PageA...p;ProdID=24273 ://http://www.ukdj.com/index.asp?PageA...p;ProdID=24273 ://http://www.ukdj.com/index.asp?PageA...p;ProdID=24273 in a large glitter lamp, like a lava lamp but glitter but find the paint seems to burn off after a week of use and then it is just like a normal reflector lamp, anyone recommend a particular lamp or any lamps that the glass is actually red in colour and its not just red paint they use. Must be reflector type as the heat activates the glitter. Link to comment Share on other sites More sharing options...
musht Posted October 31, 2007 Share Posted October 31, 2007 Dichroic filter wouldnt be cheap in a larger size but would last or possibly stained glass on top of a clear lamp. Link to comment Share on other sites More sharing options...
richardc1983 Posted October 31, 2007 Author Share Posted October 31, 2007 OK thank you. Ive been looking at dicroic filters, seems expensive. I was also looking at par38 lamps but this are too big for my fixture although they would fit in they dont do a 60w in the red variety only a 80w which I think would be too hot considering my lamp rated at 60w.

musht Posted October 31, 2007 Share Posted October 31, 2007 Might be able change the lamp holder and use a coloured GU10: http://www.luxurylighting.co.uk/gu10-colou...amps-1089-p.asp these have a sealed on dichro colour. PAR38 , like all Par lamps is measured in 1/8s of an inch, so 38 is 4 3/4" diameter. Link to comment Share on other sites More sharing options...
andylights Posted October 31, 2007 Share Posted October 31, 2007 I would think very carefully about changing the lamp for another type. These Glitter/Lava lamps are designed for a specific lamp than produces a specific temperature, to produce the convection currents in the liquid or to melt the wax (in the case of Lava Lamps). Using another lamp might produce too high a temperature that could shatter the bottle. Stick to the correct lamp and just buy some high temperature glass paint from a craft shop, to touch up the lamp when it needs it. It's available in all sorts of colours.

richardc1983 Posted October 31, 2007 Author Share Posted October 31, 2007 Cant seem to find any online? Theres no craft shops round here. Link to comment Share on other sites More sharing options...
musht Posted October 31, 2007 Share Posted October 31, 2007 Agree that changing lamp would be after due testing, GU10 will dissapate heat differntly from a conventional reflectoe lamp, LV lamps are no go because of dichroic mirror on back means the beam is too cool. Colorine, Rosco`s lamp colouring product is only rated to 40W, glass paint won`t even take that from experience. Link to comment Share on other sites More sharing options...
Chris Beesley Posted October 31, 2007 Share Posted October 31, 2007 Would it be worth trying a branded lamp such as Sylvania or GE ?? Link to comment Share on other sites More sharing options...
Wuddy Posted October 31, 2007 Share Posted October 31, 2007 Agree that changing lamp would be after due testing, GU10 will dissapate heat differntly from a conventional reflectoe lamp, LV lamps are no go because of dichroic mirror on back means the beam is too cool. Colorine, Rosco`s lamp colouring product is only rated to 40W, glass paint won`t even take that from experience. GU10 is not dichroic it has an aluminimised reflector, GZ10 is dichroic, a GZ10 has a square shoulder at the rear of the lamp so that it will only fit into a GZ10 compatible lamp holder, a GU10 lampholder has a chamfered internal edge so a GZ10 won't fit in. A GU10 lamp which has a chamfered shoulder at the rear will fit into either lampholder. This is to stop you fitting a dichroic lamp, which dissipates its heat rearward, into a non dichroic installation. A lot of international lighting manufacturers are only supplying GZ10 lampholders with their products, either through ignorance or as a cost thing so when installing GU/GZ10s you need to check you've got the correct lamps.

Don Allen Posted October 31, 2007 Share Posted October 31, 2007 Although the Colorine FAQ states it is only for 40 watt lamps Colorine faq it will work on 60 watt but not 100 watt. See ALIA post Link to comment Share on other sites More sharing options...
andylights Posted November 1, 2007 Share Posted November 1, 2007 The glass paint I was thinking of is called Vitrea 160, made by Pebeo (a French company). I've successfully used it on 60w lamps, to stop the same problem as described by the OP. Google returns loads of links. Note, the instructions state " leave to dry for 24hrs, then bake at 160'C". Don't bake your lamps ! Just leave to dry.... Regards, Andy Link to comment Share on other sites More sharing options...
adam2 Posted November 1, 2007 Share Posted November 1, 2007 Would it be possible to use a clear lamp and some red gel ?might be more heat resistant, and the gell could be replaced frequently for very little expense as only a small piece would be required.

richardc1983 Posted November 1, 2007 Author Share Posted November 1, 2007 I tried using par 36 gel and it just melted straight away, the intensity of heat from the bulb is too much. Link to comment Share on other sites More sharing options...
mark_s Posted November 1, 2007 Share Posted November 1, 2007 How about trying HT gel or heatshield and 'normal' gel? (Edited to make it clear what I was actually saying) Link to comment Share on other sites More sharing options...
