Very flat recessed light for mounting behind existing glazing on thin wings or tail units. The waste heat on the mounting level is dissipated on a special aluminium core PCB, which is why these lights only have a 7mm headroom. The scope of delivery contains an optionally usable, self-adhesive heatsink and mounting screws. For longer operation time, the heatsink can be placed underneath or above, depending on the space available.Please note that high-performance LEDs can get very hot, up to 70°C is quite normal. In delivery state, these lamps are only suitable for normal operation from 5 to 10 minutes when paying attention to a slight air flow. Please check operation temperatures after installation and ensure sufficient air cooling.
