57 Watt Lamp Ballast 
Microcare 57 Watt Lamp Ballast is designed to drive a CFL lamp as used in Street Lights.
The unit is designed to operate the lamp at maximum efficiency from a 24 volt DC source, while the ballast is dimmable for power saving solar modes. The ballast is designed to strike and operate the lamp over a range of 18 to 28 volts input.
The unit has closed loop power regulation to improve lamp life.
Features:
- Input voltage range of 18 to 28 volts DC
- Closed Loop Power control
- Closed Loop preheat current control.
- Controlled preheat time.
- Automatic restart.
- Full lamp fault protection.
- Over temperature protection
- Fully protected against lamp or filament failure

Solar Street Light Controller with MPPT
Microcare MPPT Street Light Controller utilizes PWM and integrated technology to provide greater than 97% efficiency from your solar panels. The actual charge current increase you will see varies primarily with module temperature and battery voltage. In comfortable temperatures, current increase typically varies between 10 to 25%, with 30% or more easily achieved with a discharged battery and cooler temperatures.
The controller has a pin selectable battery low voltage cutout. The turn on time for the load is programmable. The factory setting is On at dusk and Off at dawn. The controller can be programmed for ½ hour, 1 hour or 1.5 hours after dusk or before dawn operation. What you can be sure of is that the Microcare MPPT charge controller will deliver the highest charge current possible for a given set of operating conditions.
The ability to step down a high voltage solar array to a low voltage battery can save you money by reducing the size of the cable required and making the installation simpler and faster.
