Wholesale LED Panel Lights 600×600 from China<\/h1>\n

The 600×600 panel is the office ceiling of the world. It drops into the same grid the old fluorescent troffer occupied, and it sells on three things an installer notices in the first week: whether the light is even across the diffuser, whether it hums on the dimming circuit, and whether it still looks new after a year in a heated ceiling void.<\/p>\n

\"Square The photograph shows a representative panel from the category. Driver type, dimming and frame finish follow the order sheet, and the image is illustrative rather than a picture of your goods.<\/p>\n

We have sourced panels out of Zhongshan and Jiangmen for five years. Three failures keep coming back. A light guide plate made from regrind material yellows within months and shows it around the edges first. A panel shipped with the quoted driver brand arrives with a generic one, which is invisible until the dimming circuit misbehaves. And a panel that tested evenly at the sample stage shows dark corners in bulk because the guide plate changed supplier.<\/p>\n

This page covers what the optics and driver words mean, what belongs on the order sheet, and the checks that catch a weak lot. The cluster map behind the category is in our wholesale lighting overview<\/a>.<\/p>\n

Optics, driver and frame: the three decisions<\/h2>\n

The light guide plate is the panel’s optical heart. Light from the edge-lit LEDs travels inside a PMMA sheet whose pattern spreads it evenly downward. A virgin-material guide plate stays clear; a regrind plate yellows and develops edge glow. The difference is invisible on day one and obvious after a summer in a warm ceiling, which makes the guide plate the first item to pin down in writing.<\/p>\n

The driver is the second decision and the one installers notice first. A branded driver with a dimming protocol agreed in advance behaves on the circuit; a substitution does not, and dimming complaints are the most common warranty call in this category. The driver also carries the panel’s safety approval in most builds, which means a driver swap can invalidate the certificate that shipped with the goods.<\/p>\n

The frame is the third decision and the cheapest to get right. An anodised or powder-coated aluminium frame resists the yellowing that painted frames show under UV. Recessed, surface-mounted and suspended builds share the same panel but need different mounting kits, and the kit list belongs on the order sheet rather than in an email.<\/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 chip and driver prices move; send us the size, the dimming protocol 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 panels are driven by driver procurement and guide plate production, and a single driver and colour combination is the most consistent first order. Our sourcing service<\/a> covers the factory screening, the sample round and the verification tests below.<\/p>\n

What the glare and uniformity words mean<\/h2>\n

Uniformity is what the eye sees before it reads a number. An even panel has no bright spots over the LED edge and no dark corners; a poor one announces itself in a finished ceiling. The check is visual and immediate: light the panel against a plain wall and look at the corners and the centre. Any regrind or layout problem shows there.<\/p>\n

Glare is the number that office specifications are written around. A panel with a micro-prism diffuser achieves a lower glare rating than a plain opal diffuser, at a cost. If the panel serves offices where a lighting designer is involved, the glare requirement belongs on the order sheet as a figure, because it decides the diffuser and the diffuser decides the price.<\/p>\n

Two practical points complete the picture. Panels ship flat and stack well, but corner damage in transit is the most common arrival claim, and corner protection is a packing decision. And a panel that will be wired to an emergency circuit needs the emergency variant agreed at order time, not discovered by the electrician.<\/p>\n
