Not sure if I'm posting this in the right place but...

Dug out my old christmas tree ready to get put up and thought of an idea with it :idea:

Its one of those fibre optic ones with a bulb in the base and a spinning coloured disc so the colours are transferred along the optics to the ends of the branches.

What about if I replace the bulb with a flood, bin the disc and let the flood run its internal program 8)

That way you'd see the colours mixed not the seperate LED 's and it would cycle nicely through the 2 Million colours available and the whole tree would be lit =D>

Good Idea or Bad :?:

Merry Christmas anyways

well, it sounds good, but remember to place the flood several inches away from the fiber optic ends that way the colors can mix properly.

I tried this on someone else's (small) fibre optic tree using a GEM and it worked a treat. I'm not so sure about the FLOOD though because the LEDs are not so close together. You've got to imagine how much light doesn't go up the fibres when you place them in the beam. I think two GEMs side by side would be better on a bigger fibre bundle.

i helped a buddy of mine make a fibre-tree for his physics thesis and we used a gem to light it and it came out really nice we used a diffusion filter to make the light spread better. so i guess you could use a flood but you might want a diffusion filter i think that you mmight be able to get a dome one to make up for the lack of light source from the center of the flood

Well ordered my two interior floods and put two plug 'n' play GEMs on the order :!:

When they've arrived I've just quickly shoved the 2 GEM's into the base (along with the 5 mtrs of cable each) to see what it would look like and hoped it worked [-o<

To say the effect is mind blowing is an understatement :shock: 8) 8) 8) :D

Planning on tidying the base up and playing with my digital camera to see if I can get some nice piccies posted \:D/

While playing about with the GEMs placement (just balanced in the tub on the cable at mo) I can see how at times some of the fibres show slightly different colours as the LEDs mix :!:

It needs sorted :!: :!: :!:

Perhaps you could get a bit of diffuser from a flourescent light fitting... the sort I have in mind is a series of tiny pyramids that would collect and mix the individual colours. I can picture loads of these long rectangular diffusers in office buildings... they smash easily!
