G'day,

I'm just moving up to being a mobile DJ and I've got some equipment I'd like to use but I'm scared it will overload the system...

For instance; does a 1500w strobe use 1500 watts? If so, then how would I use this along with all my other gear (keeping in mind that a simple power board can only manage 2400 watts).

cheers

This is funny. I'm not sure of how it works down there, but how many amps is this light, and the voltage?
 

Hi mate

Strobe lights are firstly an intermittent load and secondly the 1500W will refer to its output and not to its power consumption. Strobe lights actualy use very little power so you should be fine.

sweet, cheers mate :)

Looking to upgrade the whole system (sound + lights) and yer the numbers freeked me out a bit. So when I'm shopping about I'll just take a lot at the power consumption then.
 

True, but if an output is 1500 W, it has to have an input of MORE than that, as nothing is 100% efficient.
 

High mate

Don't confuse the very brief high level instantanious light output with the power consumption. The light output is produced by a high intensity flash caused by discharging a high voltage through a gas in the flash tube. This high voltage is generated by charging a capacitor and then discharfing it across the flash tube. The power consumption (Ie Watts X Time) is very small.

A similar analogy would be a low energy flourecent lamp that you might use at home. A 7 Watt flourecent will usualy output the equivilent light of a 60Watt standard lamp. Or the flash gun for a camera which can produce the equivalent light level of a 1000Watt bulb but only for a fraction of a second and runs for weeks on 2 1.5V AA batteries.
