CFL + Bugzapper = Battery Operated Camping Light

CFLBugzapper_01_20

Knowing different ways of generating light is a great skill to have, so go ahead and add this one to your arsenal by combining a Bugzapper with a CFL Light Bulb.

Sure a CFL(Compact Fluorescent Lamp) works just fine on its own if you have AC mains, but what we’re talking about here is getting the light bulb to work off of a single D battery. We featured a similar hack a few months back by using a Joule-Thief to get the high voltage for the fluorescent tube, but if you can’t get your hands on discrete components, [Jan] shows us another way by gutting a tennis racket bugzapper for its booster board. Knowing that the bugzapper steps up the 3V to about 2000V, he decided to see if that same circuit would run off a single 1.5V D battery and achieve the voltage required to drive a CFL tube. After carefully removing the electronics from the CFL housing, [Jan] was able to directly connect the booster board to the electrode wires of the fluorescent tube, and voila; he now has a D-Battery operated camp light that has a run time of over 200 hours.

It would be interesting to see how this hack compares to the Joule-Thief method in terms of brightness and run-time. Before you go and scrap the parts out of the CFL light bulb, make sure you check out this detailed breakdown of popular CFL light bulbs.
