I love it! I like the way you used the other string of lights "as an extension cord", but you were probably more concerned with using it to take advantage of its 3 amp fuse!

Preheat Fluorescents forever!

LOL i did actually think about the 3a fuse when using that extra string of lights. wasn't quite sure if that crazy-fluorescent-thingie would work when fired up on DC

Also not uncommon for me to use a string of lights as an extension cord for low wattage things LOL all depends on whats closer/easier to grab at the time

Maybe the 'next generation' of this will be AC again...and have some flasher bulbs (but that'd be a video instead of a still image )

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

LOL The flasher bulbs are HILARIOUS! They make the lamp go crazy, but it stays lit!

Tried that today using a F20T8 lamp and a 65W ballast, along with a bridge rectifier.

Using a capacitor to smooth the DC output was not too good, scratch the first bridge rectifier, fried one diode in it. The lamp would not light with DC supplied, the starter glowed really bright and the cathodes flashed bright.

Second bridge and it lights, you can move the discharge around inside with a really strong magnet, and get an interesting brightening of the coating near the magnet. Voltage across the tube varied from 55V to 58V when you bring the magnet near the electrodes. After a few hours running the tube is blackening at the anode end, when I switched off going home, running at around 33W input instead of 18W, much brighter than normal, and likely to really shorten the life of the Phillips Indonesia lamp. The ballast and the ends are from a scrapped fitting, with a new ( now very abused and sluggish on DC as only one electrode lights) S2 starter, it would not work with a S10 starter, it just glowed dimly ( and killed the noise supression capacitors of the second bridge rectifier board).

SeanB~1 - did you use an actual ballast? (I've always heard that running a magnetic ballast on DC wouldn't work & might even cause it to burn up) With the setup setup i did there was no
blackening of the fluorescent's ends (but i also did not use any capacitors)

I'm gonna have to try the magnet thing LOL

Isn't SeanB-1 in 240 V 50 Hz country? That would make a difference in having to use different "gear" for sure!

The ballast is before the bridge rectifier, and thus is running on AC.

The tube anode did blacken a little, but the 2 other tubes I tried today ( running at 65W and 130W) both melted the anode into a blob before the tube died.

I love your "extension cords"
