Note: Bolt pattern is different to original High Light boards but they will still fit with extra drilling.
These single heatsinks are predrilled for mounting the new High Light 420 boards, but can also mount original High Lights and standard Quantum Boards with extra drilling.
420 Heatsinks are slightly longer (480mm vs 444mm) and heavier (1.5kg vs 1.4kg) than original High Light heatsinks.
Heatsinks include 6mm mounting holes at each corner for ratchet hangars or aluminium tie bar connectors etc.
Whilst these are primarily designed for remote drivers, there is enough room at each end to drill two mounting holes for most Mean Well drivers if desired (please enquire).
