Inside a 4.5W LED 300mm / 1-foot T5 link light style fitting.

Not the first of these I’ve opened, but I actually like this one better. It uses the same style of loop through connector that the other fitting I took apart used, but in this instance it uses a very standard GU10 style LED driver to run a series parallel array of LEDs at 15V and 300mA. I like that little feature. The fact it uses a standard power supply that you can buy on ebay for a dollar. The LEDs are on an aluminium core PCB, or to be more accurate a strip of aluminium with a layer of fibreglass PCB material laminated on one side.
The connection system is fairly standard for these, with a “clover” style connector using copper coated aluminium wiure in the short flex provided, and a friction earthing system onto the aluminium housing.
Two naughty bits… One of the crimps inside hadn’t been crimped and popped off the twisted wires, and there was no end-cap for the end of the fitting meaning the link-through pins weren’t covered.
It’s actually quite a nice little light. This one may actually find its way into my kitchen.
