SpotLight Question

[mbandgeek]

My school has 2-15 year old Satellite 2's They are great, but they are really loud, is there anything that we can do to modify them to make them bearable to use?

Exactly what is making all the noise?

[BillESC]

Noise usually comes from the two cooling fans. Go through the fixture and tighten every screw and nut/bolt. It should reduce the noise level.

also some good teflon oil goes a long way... and make sure that your gel cuts in the boomerangs are cut well so you dont get a paper in the wind effect....

If it's not the nuts/bolts making the noise, but it's comming from the fan. take the cover off of the fan (make sure unit is in the off position) and oil the fan. Also, make sure that there isn'r anything that is hitting the fan blades.

Out spot is like 9 yrs. old and ust to make noise. We did what I said above and for the most part, it stoped.

Don't just make sure it's off- if at all possible UNPLUG IT!!! You can't imagine how many time's I've been shocked by things that are "off," and it always surprises you, too. Better safe than sorry!

Ditto. I haven't been shocked as yet but you would always unplug an item rather than just relying on a switch. If it is hardwired, find its breaker and turn it off there. There is a principle in electrical work that goes along the lines of assume that something is live until you have proven that it is dead. In this instance something like metering it and obtaining 0V or very close to it would be considered to be proving it dead. We don't want to all be sending condolences because someone decided that all they needed to do was turn the switch to "off" and that they would be right. Take for instance your television, whilever you can turn it on with a remote control, it has power running through it. It can bite in this "off" state.

The other thing to remember is that things like capacitors can hold a charge for quite a long time after being switched off. Whilst I do not expect that you would encounter them inside a followspot, it is worthwhile pointing it out so that people who are opening up other things are aware.

If you do not fell confident in doing something like this then maybe that is telling you something. I think that it would be wise at that point to refer service to qualified persons.

I realise that this has not been a short post, but we all need to stay aware of the dangers of electricity. Like I said, I really don't want to send condolences.

i assume that since you are recomending it teflon juice has a high enough flash point that it will not ingnite if i spray some on the iris, etc.

[kingfisher1]

yeah, i'm an idiot, flourocarbons dont ingnite very fast do they....
i only asked after considery spraying our schools spots with WD-40. i then realised that that might be stupid.
