In order to install and connect 12v garden lighting systems, Lumena supply 12v AC Transformers available in 4 different wattages 10w, 20w, 50w, 100w, 150w. The transformers are supplied with 1m of waterproof mains input cable with a 3 pin plug and 60cm of waterproof detachable 12v 2 core output cable. Ideally the transformers should be installed above ground on a suitable post or wall, this could be behind taller planting for example. To ensure that the correct size transformer is used, the total wattage of the 12v light fittings needs to be calculated. This can be done easily by multiplying the lamp wattages for each fitting type, (example at bottom of page). Add these totals together to determine which size transformer is needed. Remember not to overload the transformer. It is recommended that some spare wattage capacity is left in case additional 12v lights are required. It is equally important not to use too few lights or have too low wattages on a 12v lighting system as this can result in ‘overvoltage’. Transformers should be loaded to at least 70% of their capacity; for example a 100 watt transformer should power lights with a total wattage of at least 70 watts. All Lumena 12v transformers have a built in thermal cut-off which protects against power overload or ‘overvoltage’.

Seems well made, so far, so good.
Bought to replace an old 150w badged Garden Lights TDC DB-150-12W transformer which had a fault fuse connection so intermittently worked. Think somebody had over tightened it so the thread had gone or wear and tear.This unit is a direct replacement except the 12v pin out is different and it uses a 240 volt plug. The existing connection was into a weatherproof junction box. Cut the plug so the fusing is via the garage circuit that it's on. Used the 12 volt cable it came with and chocked blocked it into the cable after cutting off the old TDC 12 volt plug.Did test the 12 volt ac output before starting the job, fine. Fuse out, test with electrical probe and meter before hand just to check power was getting to the old power supply unit before diagnosing the fuse issue on it. Also took the opportunity to switch all bulbs over to LED.All was good and it works well.
