I am fairly new to this and have several (simple) question:
I have a krypton flashlight bulb (markings on bulb say 4.8v .5A). The original flashlight that the bulb was removed from used 4 AA batteries.
- Wouldn't the 6v from the batteries be 'pushing' the bulb a bit and reducing its life?
- If I want to wall-wart power this bulb, what voltage wall wart would be recommended?
- Since most wall warts (unregulated) supply higher voltage than the sticker says, what method should I use to bring down the voltage to the recommended voltage (regulator, resistor, etc) (I remember once trying to do something similar to this project and using a resistor. Even though the resistor was a high wattage resistor it got REALLY hot)
- I think this question probably will have the same answer as #3, but if I want to dim the bulb what method would be recommended?
Thanks for you assistance
