If you want to swing around 500W of light just kind of willy-nilly, the Omni Light may be for you: its a compact Quartz Halogen light with an adjustable beam, a swing-away handle, stand mounting capability, and an umbrella holder. Conveninent, yes, but bear in mind that this is 500 watts of old school Quartz Halogen output, so it will get hot as heck.
