washing a building with blue light ?

[red_robby]

I've recently been asked if i knew a good way to wash the front of building with blue light.
the building is 30' high and is clearly visible from the 401 (trans Canada hi way)
are there colored HID bulbs out there? anything else?
Umm...help?

This should be fund to watch develop. It'll certainly attract mosquitos and moths; the whirly cloud of little blue-lit dots flying around the building will be a signt to behold. And it should get a lot of hits during bird migration, if it's on a flyway. Not to mention the effects on people: http://www.health24.co.za/news/Depression/1-903,24791.asp

well...it's aupposed to attract attention to the building so I guess I'm on the right track.

I've been useing SGM Palco LED wash lights on buildings recently for temporary installations, they'd make great permenant lights too. They're actually "full" colour so you could have a bit of fun at times too!

Yeah. It used to be that they listed 'standard' colored MH lamps on their site. Seems like they offered blue, aqua, green, pink, maybe others... They offered them in the largish sizes - around 250W or so.

If you're serious, I'd suggest you post your question on sci.engr.lighting. Some of the guys there work in the lighting industry and might have some ideas.

I guess this might sound like a joke but it isn't...
I've already ordered 4 bulbs through my supplier, I'll post pictures when I'm done
thanks again for the help.

Mercury vapour lamps covered with lighting gel of your choice.

Will be the cheapest, and most effective way.

While the mercurty option is probably cheaper up front, power consumption will be a lot higher using a filtered mercury vapor lamp than using a metal halide that is designed to emit blue light (by using blue-emitting fill gases), using the colored metal halide lamp is probably most cost effective long-term, though a lot of that may depend on local cost of electricity.

You're right.

For some reason I read this as a temporary thing.

Now that I re-read the post, it does sound like they want a permanent solution.


For a long term set-up, the gels will fade also.
