24v DC driver for LED lights. Discussion Thread24v DC driver for LED lights. Electrical Advice

Hi all,

Can anyone recommend a decent 24V DC constant voltage LED driver.

It’s for an install of bathroom niche LEDs IP65 downlights. They are mini and have a 35mm cut out. The 1.5mm T&E is already dropped to each cut out but need a driver that will fit through a 35mm whole and to be pushed up.

Many thanks,
Jay

I found this video online (the veracity of which I cannot be sure) which seems to suggest 3 years for factories, and for some...
