When needing expensive software for your work such as cad and lighting design which generally have both a high initial cost and expensive annual costs to keep access to relevant features, how much of that cost can be written off for tax purposes? Does it make a difference if you are sole trader or limited. Does it make a difference if you buy outright and pay annual update fees or if you use a lease scheme?

Thanks for sharing. Would you use a touch of graphite powder on the iris if it seems rough or does that have the same issue as the PTFE?

We have some mac700 profiles and mac250 krypton in need of a good clean. Happy to strip them and clean the optics but unsure on what lubricants to reapply where needed. Manual mentions various parts that can have teflon lubricant applied but doesn't recommend anything for things like gobo wheel gears. Which teflon lubricant do people use and does anyone recommend lubricating any other parts; and with what?

thanks, I'll pass that on to the service chap. the replacement fixture has arrived now so I can just swap it out for now.

Thanks, we're going to replace it tomorrow afternoon anyway, let the hire company sort it out. If it is igniter or ballast then there's not much I can do without spares anyway. I was hoping it might be the relay sticking, but if it is; my efforts to knock it free have failed.

I'm onsite with a rig which includes a couple of mac250 entour. One of them has doused its lamp, although it worked for over a day. When trying to strike the lamp it says hot even though completely cold. I have tried a spare lamp but no change. When attempting to strike the lamp there is only a very quiet click from the yoke, not the usual sound that you get when the lamp strikes or attempts to strike. I suspect either a faulty temp sensor or sticking relay. I've tried giving the relay a sharp tap but no difference. Anyone got any ideas? We can get a replacement but not in time for tomorrows show.http://www.blue-room.org.uk/public/style_emoticons/default/sad.gif

have you got around to trying them at 1000mA?

I've had that error with Mac's before when the mains patch had got messed up and they were actually just getting pre-heat voltage from a dimmer. They worked just fine when the mains was put right so probably not the problem your experiencing if they are definately on hot power.
