Or how about a solar panel with a light shining on it?
Or a 12v battery running an inverter, with a battery charger on it charging the battery?
The solar panel idea actually might work, but it would need a light source to start it. Plus, it would have to be a high-intensity source, but LED should work for that.
Also, look what I (tried to) write for a school poem assignment:
Listen my friends and you shall hear
The buzzing that tells the mercs are near
I've searched the Restore's far and wide,
I just found a Lifeguard, a buck eighty-five!
I will run it on my CWA gear so heavy,
Oh no, it shorted, it is oh so smelly!
I run back to Restore, in desperate hope,
To replace the ballast that went up in smoke.
I find the ballast, I go back home,
I am almost ready, when I step on the lamp, NO!
The lamp is trashed, what a waste of cash,
I hang my head and shout WHY, WHY, WHY!
