WELLMAX Sunlight Series 2.0 Slim Downlight Recessed Surface Dual Mounting (9W-36W) Ultra-Slim High Luminous Architectural Lighting

The WELLMAX Sunlight Series 2.0 Slim Downlight provides an ultra-slim ceiling illumination solution designed for modern residential, commercial, and hospitality spaces.

The WELLMAX Sunlight Series 2.0 Slim Downlight featuring a high-luminous efficacy of $100\text{ lm/W}$ and a minimal boundary bezel, it maximizes light output while eliminating dark spots across the entire light-emitting surface.

A key innovation of the Downlight Sunlight 2.0 series is its patented dual-mount design, which combines surface-mounted and recessed installation methods into a single fixture.

This versatility allows contractors and lighting designers to adapt easily to varying ceiling conditions such as solid concrete or drywall cutouts without managing separate fixture inventories.

Both Round (Item UDR/SL/0/2/0/RD) and Square (Item UDR/SL/0/2/0/SQ) profiles feature a uniform depth of only $28\text{mm}$ , ensuring a clean flush-mount look.

The WELLMAX Sunlight Series 2.0 Slim Downlight spans five performance levels to accommodate diverse room scales:

9W ( $900\text{ lm}$ ),
15W ( $1500\text{ lm}$ ),
18W ( $1800\text{ lm}$ ),
30W ( $3000\text{ lm}$ ), and
36W ( $3600\text{ lm}$ ).

Operating at $220\text{--}240\text{V}$ with Power Factors of $0.5$ (9W–30W) and $0.9$ (36W), all models incorporate non-flicker technology and high color fidelity ( $\text{CRI} > 80$ ).

Available in 3000K (Warm White), 4000K (Neutral White), and 6500K (Cool White), they deliver up to 25,000 hours of operating life and support up to 15,000 switching cycles.
