slingshot82 32 Posted July 13, 2010 Report Share Posted July 13, 2010 Once they are on, you can increase the voltage until it gets very bright and hot then they either melt or as they often did just crack open and fail. One of our favourite tricks was to stick a 12 volt capacitor 100uf into the 240V rails. They sound like a shotgun and it snows but a bit whiffy though, sorta like fish Phantom But can you decrease voltage to dim them? I remember a lad in my electronics class at school put a 12v dc. LED in a 240v plug socket, that sounded like a shotgun too and lit the room blue with a flash lol. Kyle Quote Link to post
Phantom 631 Posted July 13, 2010 Report Share Posted July 13, 2010 Its more to do with current than voltage Vary the current with a resistor and you can vary the amount of light from the led Phantom Quote Link to post
ukhunter 113 Posted July 14, 2010 Report Share Posted July 14, 2010 i am looking to buy a lightforce 170 striker for my theoben rapid and attach it to the scope so i can go out alone.i have read the specifications of them and i think they are one of the best lamps i can get. if anyone has one could they please let me know what they are like before i depart with my cash. thanks like Kyle says they are too big and a bit of an over kill for air rifle work but if your still after a lamp kit then give me a pm as i got some deben lamp kits for sale Quote Link to post

I know about regulating current for lamps with variable resistors etc but like I said I didnt know you could do the same with LED's. Cheers Kyle Quote Link to post
