Micro OSLON SSL80 Colours The Micro OSLON is a compact light source built on a substrate of aluminium thermal optimisation. It’s unique design allows for a secondary optic to be used with the Micro OSLON to narrow or widen the beam angle. Micro OSLONs use Osram OSLON SSL LED’s and are one of the smallest high-power lensed LED’s available allowing for a compact form with maximised flux over area. At just 11mm in diameter the Micro OSLON is the smallest LED Light Engine available from Intelligent LED Solutions.
