Parabolic Aluminized Detector Lights

I have a 235 watt new technology PAR bulb (far better than LED's in terms of efficiency). I want to power the bulb with a 12 volt battery. Do I need an inverter? I know the bulb can run off of 120v-277v at 2.6 amps and 5.2 amps respectively. I only have 12 volts. Look up IUNU for info on the bulb/technology. Thank you.

I'm surprised that you say that your PAR is much more efficient than an LED. Wikipedia claims "PAR cans are being replaced in some applications by , which use less  and produce a wide array of saturated colors without the use of color filters, when white light is not needed." What technology does your bulbe use?

At any rate,  it sounds like you'll need an inverter if you stick with that bulb. If you don't, we've found very efficient 12 V LED's with reflectors, probably not good PARs, for about $14.
