I bought a new Compact fluorescent bulb and I fitted on my screw bayonet e27 bulb fitter but the bulbs didn’t burn or got overheated. I got a used Cfl bulb in somewhere in my house but it’s still functionally operating well
The electrode filaments get preheated in the presence of oxygen, which burns them out quickly and the preheating stops as soon as one of the electrodes is broken. I wonder, whether cold start CFLs would behave the same?
@@coalthedergsune I know that many cold start CFLs can be converted to hot start by adding a thermistor parallel to the starting capacitor, I have done that :) But you may also be right in some cases :)
Is this not a huge mercury contamination risk. Mercury vapour is heavy and will sink into the floor and carpet. Mercury is bound to the fluorescence and comes off in powder which needs to be carefully cleaned up. The risk is probably small but it's good to be safe
reminds me of what the baseball floodlight did after it got hit. glass broke, and it did this (when it got dark), replaced with an LED flood ); but the field needed it. anyways i now have the fixture and am going to convert it back to metal halide.
The 2nd CFL you showed, I can’t believe that some arcing went up the tube.

I like the way Cfls save the world as energy efficient. You know LEDs and Cfls are eco friendly type of energy saver lights

they would most likely have an internal arc-over or some other crazy shit.
@@coalthedergsune Probably, or the starting capacitor would hit the electrodes with instant current and break them in a fraction of a second :D
@@mercuryvaporglow5317 cold start cfls have no filaments, just little electrodes.

Where’d you get the Phillips bulb tester
Nice!
Cool!
Nice EOL's
