I need to find a housing connector for an LED
I don’t know what housing or heatsink you are using or even power supply, but if the connector is a problem, you need help and they need something fool proof.
My simple solution would be to attach them to small obsolete circular CPU heatsink so that a fan is not needed for 5W.
For power I would derate 25% approx and run two Red LEDs in series with a Molex connector. You can get that from a scrap PC as well used on HDD’s and use the 2 blk gnds and red 5V for easy connection to a tower or 5.0V &gt;=1A DC regulator with mating socket (F). Then make a cable of suitable gauge for the length.
The wires ought to be soldered then with strain relief like polyurethane subfloor adhesive dabbed around the wire shank or &lt;1cm connection as the solder connection may be fragile.
