High Power LED Driver Circuits: 12 Steps (with Pictures) shown below, i added R4 an a switch in parallel with R3. so with the switch open, the current is set by R3, with the switch closed, the current is set by the new value of R3 in parallel with R4 more current. so now we've got "high power" and "low power" perfect for a flashlight. perhaps you'd like to put a variable resistor dial for R3? lamp power supply | eBay Find great deals on eBay for lamp power supply.

High power adjustable switching power supply (SMPS) 3 60V 40A High power adjustable switching power supply (SMPS) 3 60V 40A . This switching power supply was built because I needed a powerfull adjustable bench power supply. Linear topology would be unusable for this power (2400W = 2.4 kilowatts!), so I chose a switching topology of a two switch forward (half controlled bridge). MOSFET as a Switch Using Power MOSFET Switching When using the MOSFET as a switch we can drive the MOSFET to turn “ON” faster or slower, or pass high or low currents. This ability to turn the power MOSFET “ON” and “OFF” allows the device to be used as a very efficient switch with switching speeds much faster than standard bipolar junction transistors. High power electronic ballasts for medium pressure UV ... There are two types of ballasts: electromagnetic (EM) ballasts, essentially line frequency transformers, with or without external components or controller, and electronic ballasts normally referred to as switching power circuits. Both types of ballasts can regulate lamp power, what is essential to establishing and maintaining a UV process window.
