As lighting manufacturers produce more energy efficient LED light fittings with smaller LED Drivers the need for larger LED Drivers is no longer necessary.
Having just been released in April 2018 Huibolong have developed their range of ultra compact LED Drivers.

This model gives an 18w LED output.
SaveMyLight is the only retailer of these LED drivers.

NOTE: The minimum load for this unit is 15w at 300mAH. If you do not meet the requirements the unit will flash on and off repeatedly!! This is not a fault. Please do not purchase until your electrician has checked your circuit power.
