COB vs SMD LED Downlight Housing — Which One for Your Project?
COB and SMD LED downlight housings differ in three key aspects: beam control, thermal performance, and unit cost. For residential projects under 12W requiring focused beam output, COB housings deliver superior beam uniformity with 15°–60° reflector-controlled angles. For commercial projects requiring 15W+ output over wide areas, SMD housings provide 120° native beam spread with better […]
