One to three heads
The reference tables list single, double and triple-head versions. A multi-head fitting needs a model-specific opening drawing; “Ø55 mm” is described per module.

BL-55 Multi-Head Anti-Glare LED Downlight
A modular recessed downlight family with single, double and triple-head arrangements in COB or SMD versions. The reference specification lists a 55 mm opening per module, not one 55 mm opening for an entire multi-head body. Confirm the complete cut-out drawing and selected light engine before installation.

Modular ceiling layouts
Coordinate multiple light points in one visual family.
The BL-55 series uses round and square trim concepts with several head counts. Its COB versions list narrower beam choices, while SMD versions list a 60° distribution. Select the complete housing, driver and ceiling opening as a matching system.
Focused beam choices
COB rows list 15°, 24°, 38° and 55° with 5–7W per head. Confirm the exact shielding and photometry for the quoted optic.
Wider listed beam
SMD rows list 5–8W per head and a 60° distribution. COB and SMD engines should not be assumed interchangeable in one housing.

Ceiling coordination
Confirm the full cut-out, not only a module size.
For two or three heads, opening shape and spacing can differ from a single 55 mm hole. Request the actual installation drawing and test the selected COB or SMD assembly before cutting.
- Choose head count, round or square trim, and COB or SMD engine.
- Obtain the complete multi-head ceiling-opening drawing.
- Confirm driver, beam, CCT, glare treatment and current photometry.

Technical data
Compare the published BL-55 configurations.
The table retains separate COB and SMD rows. Power figures for multiple heads are shown per head, as on the reference specification.
| Version | Power notation | Published body size | Listed beam | Light source |
|---|---|---|---|---|
| COB round single | 5–7W | Ø63 × H52 mm | 15° / 24° / 38° / 55° | COB 1304 |
| COB square single | 5–7W | 63 × 63 × H52 mm | 15° / 24° / 38° / 55° | COB 1304 |
| COB double | (5–7W) × 2 | 130 × 63 × H52 mm | 15° / 24° / 38° / 55° | COB 1304 |
| COB triple | (5–7W) × 3 | 185 × 63 × H52 mm | 15° / 24° / 38° / 55° | COB 1304 |
| SMD round single | 5–8W | Ø63 × H52 mm | 60° | SMD 2835 |
| SMD square single | 5–8W | 63 × 63 × H52 mm | 60° | SMD 2835 |
| SMD double square | (5–8W) × 2 | 130 × 63 × H52 mm | 60° | SMD 2835 |
| SMD triple square | (5–8W) × 3 | 185 × 63 × H52 mm | 60° | SMD 2835 |
The Ø55 mm cut-out is a per-module reference, not a complete multi-head opening. Request the current full cut-out and driver drawing for double or triple bodies.

Product FAQ
Questions before specifying?
We can confirm the exact options, compatibility and photometric data for your project configuration.
Does every version need only one 55 mm ceiling hole?
No. The reference specification says 55 mm per module. Obtain the complete cut-out drawing for the chosen double or triple-head body.
Can one housing be switched between COB and SMD?
The reference specification describes them as separate versions. Do not assume interchangeability without a current approved parts list.
How do COB and SMD optics differ in this family?
The reference tables list 15°/24°/38°/55° for COB and 60° for SMD. Use current photometry to choose for the target surface.
Can the head count and trim be mixed across a project?
The reference tables show several arrangements. Confirm finish, ceiling openings, power and controls for each selected version to keep the installation consistent.
