Title: Is this LED driver suitable?
Post by Dave1948 on Jan 23rd, 2016, 4:53pm

Hi everyone, I have installed some cheap imported LED ceiling lights and the circuit will occasionally trip, rarely on start up but frequently after anything from 30 minutes to 5 hours or more of being switched on. I feel confident regarding the wiring and literature searches has revealed that cheap electronic LED drivers can often do this. I did consider upgrading the MCB from B to C but I have decided to try a different approach first.

The lights have individual drivers, 240v in; 18-24v DC @300mA out, and I have a total of 6 lamps. I was considering removing the individual drivers and wiring the 6 lamps to a single driver. I have found a good quality branded driver rated at 24v 50watts  @ 2.1 amps. Is this suitable to use as the output would be the equivalent of 350mA per lamp.

350ma x6 is 2.1 amps 24w at 24v is 1 amp so just about the same will it work don know as leds are very specific in operation

Buy 'cheap'....you get what you pay for.

Changing to a C type would be no use if it's not a problem of switch on surge.

Sounds like perhaps you have one which is failing.

Hi,

I would probably look at investing in a better LED see what the outcome would be for that as the cheap imported LED ceiling lights seem to be giving you problems.

Hope this helps!  :)
