Hotel renovation, retail boutique and shopping mall lighting projects often need large quantities of recessed downlights. Many project designers and lighting importers send RFQ every month to source durable aluminum downlight housing. A wrong choice of lamp housing will cause installation delays and after-sales problems on site.

If you are preparing a lighting project quotation or planning bulk procurement, this guide shares practical points to select suitable aluminum downlight housing before you send RFQ to Chinese manufacturers.

1. Aluminum housing VS PC housing for commercial projects

Most long-hour commercial lighting projects prefer aluminum downlight frames. Aluminum offers better heat dissipation, which extends LED chip service life. PC housing is lighter and cheaper, more suitable for short-time residential usage.

• Aluminum housing: hotel, supermarket, brand retail store, long operating hours
• PC housing: apartment, short-time usage residential lighting

2. Key parameters you should list in your RFQ

Complete information helps suppliers provide accurate quotation quickly and avoid multiple rounds of confirmation. Please include these points inside your inquiry:

• Cutout size: round or square, exact opening dimension for ceiling
• Adjustable angle: fixed beam or rotatable adjustable frame
• Surface color: matte white, black, silver
• Quantity: trial order or full project bulk demand
• Special requirement: anti-glare structure, customized appearance

3. Common installation issues on construction site

• Housing spring clip size mismatch, cannot fix tightly inside ceiling
• Poor heat dissipation leads to frequent light failure after several months
• Inconsistent surface color among different production batches

We recommend confirming sample first for big project orders, to check dimension, color and assembly compatibility before mass production.

4. Custom service we support for project RFQ orders

• Standard mold aluminum downlight housing in stock for fast delivery
• OEM customized size and appearance for special project demands
• Laser print customer brand logo on lamp housing
• Mixed container loading together with track light frames and magnetic track rails
