Hi all,
I purchased two lights some time ago which unfortunately whoever removed it, left the driver behind.
A friend took a look who is an electronic engineer and has found the following out.
* There are 350 x 3w 24v light bulbs.
* They are wired in parallel using 3 x lives.
The 3 x lives means that the many light bulbs of each light fitting can be powered on in sets of 1/3rd at a time, this would give them a flicker or a pattern of some sort.
To power all of the lights on at the same time on the smaller fitting would require a 40a 24v power supply.
We think that having all 350 bulbs on at full power would be a little too bright and would like to be able to lower the power or dim the lights.
As my friend doesn't know of an off the shelf product, is there a clever power supply:-
a) that could drive all of the lights (40a 24v) which is adjustable to vary the brightness?
b) that could drive the x 3 live feeds (I'm guessing 15a 24v) independently on a variable timer & with variable power so that can play with the brightness and rotation time of the 3 groups of lights in order to achieve the original light pattern as designed?
My minimum requirement is I suppose is as in a) just to turn "all lights at once" on but with variable brightness. But my hope is b) to be able to play with 3 groups.
I have found something that could power all lights on at once below, but it is a little expensive, however it does have a power control.
Power Supply Found
I tried to attach a picture of one of the light fittings but it was too large a file. I will try again later.
It came from the outside of a Revolution pub in another town.
To my mind it was very similar to a fun fair light in that the pattern of on/off of many grouped bulbs forms a wave or flashing appearance.
