Aluminium Extrusion in the UK

randilio1 · Jan 28, 2020

Trying to find aluminium extrusion for a custom light fixture. Using 20mm star led boards have 13 3W leds spaced over 800mm±100mm. Anybody got any ideas or sources? Ideally in the UK to keep costs down. Cheers

Kinda, not many options for mounting though. Appears to rely on thermal epoxy for mounting. Thanks though

I would look on alibaba or similar for what Scrubber_steve posted and then drill/tap some mounting holes for the LED pucks. You'll still want to use some thermal paste/thermal interface material on the backs of the pucks but the Alu with fins will act as a great heatsink.
