SMD LEDs use 0.3mm epoxy coating (IP68 fails <72hrs), requiring ±0.05mm alignment and 45min/module repair. GOB employs 3mm silicone encapsulation (IP68 >2000hrs), allows ±0.5mm tolerance but demands full-layer recuring for defects. SMD operates -20-60℃, GOB withstands -40-85℃ with 6×10⁻⁶/℃ thermal… Read More »What is the difference between SMD and Gob LED

Gob uses glass substrates (≤0.7mm spacing) requiring whole-module replacement when damaged, while COB employs PCB boards (≥1.2mm spacing) enabling single-point repairs. COB’s copper heat pipes maintain 45℃ at 2000nit brightness vs Gob’s passive cooling reaching 68℃. MTBF: 15,000h (COB) vs… Read More »What is the difference between Gob and COB
