Wholesale LED Downlights from China<\/h1>\n

The downlight is the fitting that hides in the ceiling and gets judged from below. It sells to contractors by the cut-out size and to homeowners by the light it throws, and it fails on the one thing neither sees: the temperature inside the ceiling void, which decides how long the driver and the LEDs actually last.<\/p>\n

\"Round The photograph shows a representative fitting from the category. Cut-out size, trim finish and driver type follow the order sheet, and the image is illustrative rather than a picture of your goods.<\/p>\n

We have sourced downlights out of Zhongshan and Jiangmen for five years. The same three failures come back. A heat sink sized to pass a bench test runs hot in an insulated ceiling and shortens the light’s life to a warranty claim. A spring clip that holds on the sample room ceiling falls out of a thick plasterboard one. And a fitting sold as dimmable stutters on the circuit it was never tested with.<\/p>\n

This page covers what the thermal and optical words mean, what belongs on the order sheet, and the checks that catch a weak lot. The wider cluster picture is in our wholesale lighting overview<\/a>.<\/p>\n

Thermal design, optics and the cut-out<\/h2>\n

Heat is the design problem. An LED downlight converts most of its input into heat, and that heat has one way out: the heat sink behind the ceiling. Die-cast aluminium sinks spread heat far better than stamped steel, and the difference shows up as a temperature number after an hour of burning. A fitting that runs cool lasts; a fitting that runs hot dies early and takes the driver with it.<\/p>\n

Insulated ceilings change everything. A fitting rated for free air can cook inside an insulated void, which is why some markets require an insulation-contact rating for fittings that touch insulation. If your market needs it, that rating belongs on the order sheet, because the build differs and the certificate follows the build.<\/p>\n

The optics decide what the customer sees. A deep recessed reflector with a matte black baffle cuts glare and reads comfortable; a shallow fitting with the LED close to the trim is cheaper and harsher. Beam angle is the other variable: a narrow beam suits counters and artwork, a wide beam suits general rooms. Both belong on the order sheet as numbers.<\/p>\n

Specifications and minimum order<\/h2>\n

Our minimum order is 1 piece, so you can start with a single unit and scale up once the sample is approved. Every line below changes what the factory builds. We do not print prices or schedules here, because driver and housing inputs move; send us the cut-out, the beam and the quantity, and we come back with a live quotation and a firm production slot.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Minimums in this category track die ownership: a standard cut-out and finish runs from stock tooling, while a bespoke trim or size means new tooling. Our sourcing service<\/a> covers the factory screening, the sample round and the thermal checks below.<\/p>\n

What the dimming and rating words mean<\/h2>\n

Dimming is a pairing, not a feature. A dimmable downlight behaves on the dimmer types it was engineered against and misbehaves on others, which is why the compatibility list matters more than the word dimmable on the box. Ask which dimmer families the driver has been tested with, and put that list on the packaging if you sell to consumers.<\/p>\n

Ratings follow the ceiling. Fire-rated fittings add a barrier that contains fire through the ceiling void, and they cost more because the build differs. Insulation-contact ratings decide whether the fitting can be buried in insulation. Both are market requirements rather than preferences, and both change the housing, so they belong at order time.<\/p>\n

Two practical points finish the set. The spring clip is the part installers break first, and its wire gauge is worth a line in the specification. And the connector between driver and fitting is where electricians judge the product: a proper locking connector costs cents and reads as quality on every install.<\/p>\n
