An ultra thin lighting element including at least one light source. Automatic precautionary checkpoints are made at regular time intervals when computational time exceeds a preset value. Diamond material 104, on account of its extremely high thermal conductivity, is a preferred choice of heat spreader which permits build up of thermal energy in the mirror 100 to be quickly and evenly distributed across the entire mirror surface, increasing the working life of the mirror. Additionally, an average displacement of the CMTL is computed.
