APL-TD-4415

Product origin China

5W-22W options in 40-45mm slim profiles. "Small cutout, large faceplate" design fits Φ75-200mm openings. SMD2835 source (70-80lm/W efficacy), AC160-265V input. PP housing with steel heatsink. 70-80 CRI, non-dimmable (PF≥0.5). EU/ASEAN certified. Ideal for warehouse/industrial retrofits.

I. Revolutionary Form Factor Architecture

"Small Cutout, Large Faceplate" Design Philosophy

Core Innovation: 80-130mm faceplates conceal 75-120mm openings, covering ceiling irregularities (±3mm tolerance)
Engineering Benefit: Maximizes light emission area while minimizing structural intrusion (H40 slim profile)
Retrofit Advantage: Single downlight fits multi-generational cutouts in EU/Asian buildings

II. Power Scalability Platform

Wattage	Faceplate Ø	Cutout Ø	Lumen Output	Application Profile
5W	100mm	Φ75mm	350-400lm	Niche accent lighting
7W	110mm	Φ90mm	500-560lm	Hotel corridor zones
12W	120mm	Φ90mm	840-900lm	Retail task lighting
18W	130mm	Φ120mm	1,260-1,350lm	Industrial workbenches
22W	150mm	Φ150mm	1,540-1,650lm	Warehouse aisle lighting
(Custom)	180-220mm	Φ200mm	2,200lm+	High-bay pre-rollout

Note: All variants maintain constant 40-45mm depth - industry's thinnest multi-watt solution

III. DOB Technology Integration

Driver-on-Board AC Direct System

Circuit Topology: Passive PFC buck converter (No IC - discrete components only)
Voltage Optimization: Narrow-range AC160-265V targeting stable-grid regions (SE Asia/Latin America)
Thermal Management:

22W model: Cold-rolled steel heatsink (1.2mm) with 48 fins
≤18W: Die-cast zinc alloy base
