Just like the incandescent bulb earlier than it, the compact fluorescent (CFL) bulb is quickly fading into obscurity as there are fewer and fewer causes to make use of them over their LED successors. However there are many issues to do with a number of the extra attention-grabbing circuitry that made these comparatively environment friendly gentle bulbs work, and [mircemk] is right here to indicate us a few of them.

Fluorescent bulbs require a excessive voltage to work correctly, and whereas this was straightforward sufficient for big ceiling installations, it was some time till this {hardware} may very well be positioned inside a bulb-sized bundle. When eliminated, the excessive voltage driver from the CFL is used on this case to drive a small inductive heating coil circuit, which may then be used to quickly metals and different objects. After some testing, [mircemk] discovered that the electronics on the CFL circuit board had been in a position to simply deal with {the electrical} load of its new activity.

When previous expertise fades away, there are sometimes plenty of attention-grabbing use instances simply ready to be discovered. [mircemk] stories that he was capable of finding these gentle bulbs at an especially low worth because of low demand attributable to LEDs, so anybody needing a excessive voltage driver board for one thing like a small Tesla coil would possibly wish to take a look at a CFL first.
