I’m not aware of anyone making such mods, it’s a risky business as you are aware. Perhaps the OSL readers might have some experience of it though. Let us know how it goes.

Hi Rob
Many thanks for a most useful website!

I’m in charge of lights in a church housing 70-100 concerts a year. We have just purchased 16 stairville par 64 led cans with which we are very satisfied for their light output. However, we are cheapskates and bought cheap lamps. They are fitted with a constant running fans, which are delivering noise output to our dissatisfaction. Many of our concerts are chamber music. I have disconnected the fan and installed a max/min thermometer in one of the lamps. I have conducted trials with different loads in 8 hour runs, and have measured a max temp of 54 deg celsius. Thats not quite uncommon in electronics. Is it safe to leave the fan off?
I’m thinking of installing thermoswitches to turn on at 45 deg celsius. Is it needed? Does anyone have any experience with these things?
Is this maybe stuff for an article ( the DIY approach to cheap lamps)?

Sincerely your grateful reader

I have 16 Martin Mac 250+, 48 Par 64 and 12 spots – All controlled by a Pearl 2004 desk.

I know I can make the effect with gobos, but I actually want the fan on the stage. So the stage look kinda industrial.

Best regards

The effect you want is normally created by a gobo (the shape of the shadow) in an intelligent light. I don’t know what kind of system you have set up there but you’d need a desk that can control the light as well as some kind of intelligent fixture. Try check a DJ equipment place, those would probably be the cheapest if not most controllable.

Im making stage and light for a mini festival for upcomming bands.

I would like to make a effect on the scene, with a fan casting shadows on the floor – Just a slow rotating fan and some white light.

Im wondering if you have any ideas how I could make this?

Thanks for a great site!

I wonder if you could give me some advice as I think I kow what would be ideal froim my point of view but I don’t know if such a thing exists. The scenario is as follows:

It’s a church congregation but we don’t meet in a traditional church building instead we use a community hall. This hall is used to staging amateur dramatic shows, pantomimes etc so has a proper stage with a ceiling mounted lighting rig infront of the stage with about 10 par cans arranged as you would expect for a stage performance.(The hall seats about 300)

The band that plays music during a service are set up on the stage but the guy who is doing the preaching uses a small raised staging area on the floor infront of the main stage.

My problem is that whilst there is plenty of light on the stage this raised area on the floor infront does not have sufficient lighting and I want to correct that. I want to buy some new lights rather than move the existing ones. I’m concerned that if I buy a theatre spot (which is what we have at the moment) and mount it on the rig pointing down at the preacher it will be really bright in his eyes and becasue of the angle of the lecturn won’t properly light that up either.

What I am thinking is if I had two spots mounted on the side of the rig pointing down at the lecturn than because the light source is at the side it will not dazzle the preacher but should hit the angled lecturn. (It doesn’t need to be mega bright just nicely illuminated).

I am not sure of the capabilities of LED lights but (and this is where I don’t know if such a thing exists) my ideal would be to have the LED lights set to give a white light with a narrowish spread and more importantly it can be turned On and Off and dimmed via a handheld remote control.

Would you be able to tell me if such a thing is possible and if not, tell me what you would advise.

Very many thanks

Thanks
