Description 50W COB LED – Solder- (Warm White) This 50W COB LED requires soldering as well as being powerful. Simply add a LIVE and NEUTRAL wire to labeled terminals on the unit, making sure the wire are secured using solder and you’re good to go. These units are extremely powerful (90-100 PAR), as well as heating up quickly, therefore require active cooling to prevent them from burning out. Andrew our resident tinker shows us just how to use these lights, as well as some technical information to boost your knowledge. The use of a COB LED Optics Lens will help to spread the light more directly downwards.
