Lighting Parts Manufacturing FAQ
How do you optimize LED heat sinks and housings for thermal dissipation?
We match the alloy and process to your luminaire wattage: high-pressure die casting in ADC12 or AlSi10Mg (96–140 W/m·K) for integrated housings, 6063-T5 extrusion (200 W/m·K) for linear profiles, and 1070 pure aluminum cold forging (220+ W/m·K) for dense pin-fin arrays. We then CNC skim-mill the MCPCB mounting pad flat (0.05 mm per 100 mm, Ra ≤ 1.6 μm) to minimize thermal interface resistance.
Can you hold IP65–IP68 sealing tolerances on outdoor lighting enclosures?
Yes. For street, area, flood and inground fixtures, we CNC machine the silicone gasket channels, lens seats and cable-gland threads to ±0.01 mm, apply vacuum impregnation when required, and perform air-decay or hydrostatic ingress testing prior to shipment.
How do you control color and finish consistency across architectural lighting batches?
Architectural trims, baffles and bezels are checked against master color plaques using a digital spectrophotometer (holding Delta E ≤ 1.0) and a 60° gloss meter, alongside ISO 2409 cross-hatch adhesion and ASTM B117 salt-spray testing.
Can we prototype housings with CNC machining before investing in die-cast tooling?
Yes. There is no minimum order quantity (MOQ) for CNC-machined, sheet-metal or 3D-printed luminaire prototypes used for UL, DLC or thermal validation. When you scale to die casting, extrusion or stamping, we build the production tooling and you retain 100% ownership of all dies and molds.
Where are your factories and how do you mitigate lighting supply chain tariffs?
Meco operates IATF 16949:2016-certified manufacturing plants in Thailand (20,000 m²) and China (16,000 m²), supported by U.S. engineering teams and corporate headquarters in Richmond Hill, Ontario, Canada. Dual-country production gives lighting OEMs tariff flexibility and redundant capacity.
