Jaycar have sold the MP3090 (Manson SPS-9400) over many years. I have one dated 2001 and they are still in their catalog in 2015. Manson is a Chinese manufacturer of medium quality power supplies, at reasonable prices. Continue reading Jaycar MP3090 / Manson SPS-9400 repair
I wrote in the fraud of energy efficient lighting – e-ballasts of frustration with green measures forced on us, measures that have replaced tried and true reliable lighting solutions with high tech low reliability solutions in a false promise of net energy saving.
Typically, the cost of repair and replacement of this unreliable technology is much greater than their direct energy saving, indeed much greater than their energy consumption of the life of the equipment.
Above is a ballast removed from a light this morning after 4 years during which it was hardly ever used… perhaps 10 hours at most… so the original capital cost of $80 for luminaire and fitting for 10 hours service gives an average cost of $8/hr for capital and about $0.01/hr for energy.

The humble flourescent light is one of those. Although still one of our most efficient lights, rivalled only by the best of LEDs, the push is on to replace the conventional magnetic ballast flourescent T8 flourescent with T5 lights, and in the interim, T8 lights with electronic ballasts.
