Glyn Edwards Posted August 11, 2009 Share Posted August 11, 2009 Can the collective power of the Blue Room help? I need to build some mobile set trucks that can be used to replicate the 70s dance floor effect for an upcoming production. Consequently I'm looking for some 12V flood type units, ideally with a greater than 90 degree beam spread and symetrical reflectors. Due to power limitations anything I get needs to be able to take a 35W lamp to fit within the dimming capacity I have available. (wireless dimming) Total budget for the project is of the order of £500 which rules out buying additional dimming capacity etc. Can anyone suggest where I can find suitable floods, preferably that don't come with transformers etc and are capable of taking a 35W lamp. All the ones I've found on the web seem to be either american or the suppliers can't tell me what lamp I can fit in them. Answers on a postcard...

adam2 Posted August 11, 2009 Share Posted August 11, 2009 Not quite certain what you require, a true flood light a greater than 90 degree beam angle and only a 35 watt lamp, is not going to be very impressive.Or did you mean something to take a 35 watt MR16 lamp ? these are available in "flood" beams, but nothing like as wide as 90 degrees.Fittings for MR16s are available very cheaply from numerous sources.

A 35W MR16 with 60 deg lamp is the back up plan. Probably in the form of a bare holder or maybe a short nose birdy. Ideally I'm after something like a shop or exhibition flood unit, sadly all I can find has some form of discharge lamp. Glyn Link to comment Share on other sites More sharing options...
swampman Posted August 11, 2009 Share Posted August 11, 2009 How large are the individual squares? And how deep? Colour: gel or painted glass/plastic?Perhaps four (halogen bi-pin lamps with holders similar to those used for dichroics) +/- 15w light sources and a reflective backing (aluminium sheet/foil) in each box. Consider heat build up and cable thickness also (practical and safety aspects)Or LEDs ?! Link to comment Share on other sites More sharing options...
mutley Posted August 11, 2009 Share Posted August 11, 2009 What about 12v cold cathodes like those used in computers? (something like this) They don't draw much current, but can't be dimmed. Otherwise, I would think about using 6x 5W lamps or another option (depending on how many 'squares' you need) is to use stripped LCD monitors with a gel in them. You'll get a 4x3 oblong rather than a square, but you might be able to get a batch cheap on ebay?.... Otherwise, I would look at using 35W dichroics with a clever dispersal reflector arrangement. Probably a glossy white or silver foil surface at a shallow angle, reflecting up onto a textured sheet of perspex, with a frosted piece of perspex a few inches above that.... Something like this maybe:http://www.stestott.co.uk/lightbox.jpg Link to comment Share on other sites More sharing options...
adam2 Posted August 12, 2009 Share Posted August 12, 2009 Very cheap mains voltage floodlights are available, intended to take a 240 volt 150 watt linear halogen lamp.It is easy to remove the lampholder and fit a 12 volt bi-pin lamp holder in the middle of the reflector, I have some lights like that. Would that serve ? mine have 12 volt 50 watt A1-220 lamps fitted, but 35 watt lamps are available. Link to comment Share on other sites More sharing options...
