it needs 220v, which in my opinion really sucks because it will never be able to be used in smaller venues here in the states where 120v is standard.
I must respectfully disagree with the statements above. I have editted for clarity, NOT to take JDs comments out of context.

Also, the light from an arc discharge lamp is given off from the arc, same as welding, same as getting a shock, same as lightning. The only effect that the electrodes have on the lamp is that as they start to burn away and the arc gets longer, the color temperature gets warmer. So, yes, a shorter gap gets you closer to a point source, but the light is not given off by the electrodes. If the light were given off by the electrodes we would be back to the black boy radiator model like T/H lamps, and the arc gap wouldn't matter.JD said:The closer the electrodes (short arc) the more effective the light source is. In DC xenon spots, the output is primarily on one electrode (thus the different shapes), sadly, ac HMI's produce two equal point sources, one on each electrode. The closer they are, the better, but there can only be one mathematical center to a parabolic, one gate cross point, and one beam convergence.
