Bridgelux 45mil 3W 700mA High Power LED Emitter – 240lm 6000K–6500K Cool White

A 3W high power LED emitter built on a genuine Bridgelux 45mil chip, delivering 220–240lm of cool white light at 6000K–6500K from a 14.8 × 7.9mm package. Driven at 700mA with a 3.5–4.5V forward voltage, it is the workhorse emitter behind street lights, flood lights, high bay and tunnel fixtures where a stable, repeatable 3W light engine matters more than a headline lumen number.

• Bridgelux 45mil chip, 240lm output – the 45mil die area spreads current density over a larger junction, holding efficacy at 700mA instead of falling away as smaller dies do. Luminous flux is binned at 220–240lm, so a design can be rated at 240lm with headroom for bin tolerance.
• 6000K–6500K cool white – the crisp white preferred for roadway and industrial visibility. A six-step CCT range from 4000K to 7000K is available from the same package, so one footprint covers warm, neutral and cool variants of a luminaire range.
• 700mA constant current drive – a 3.5–4.5V forward voltage matches common constant-current drivers, and the 700mA rating gives roughly 80lm/W at the junction temperatures seen in outdoor fixtures with proper heatsinking.

LED street lights and solar street lights, flood lights, high bay and low bay fixtures, tunnel and underpass lighting, stadium and area lighting, architectural and decorative lighting, torch and portable lighting, traffic signal heads.

Operate with a constant-current driver rated 700mA and a heatsink sized for the fixture's ambient; junction temperature is the main driver of both lumen maintenance and colour shift. The emitter is reflow solderable to standard lead-free profiles – follow the recommended ramp and peak temperature for the package, and avoid mechanical stress on the lens during handling. With correct thermal design, 50,000 hours of operation is achievable.

Each reel is tested for forward voltage, flux and colour before packing, with a defect rate held below 0.2%. The emitter carries a 2-year warranty; faulty units within warranty are replaced with new orders for small quantities, and defective batches are repaired and reshipped or settled by agreement. LM-80, RoHS, CE and SGS documents are supplied with every shipment.

Is the chip genuine Bridgelux?
Yes. The standard build uses a Bridgelux 45mil die. Epistar 45mil is available as a lower-cost alternative if your design allows it – the option is stated on the quotation so there is no ambiguity at inspection.

What driver should I pair with this emitter?
A constant-current driver set to 700mA with an output window covering 3.5–4.5V. Do not drive it from a constant-voltage supply without current regulation.

Can I have samples before ordering?
Yes. Sample orders of a few pieces are accepted for quality and bin verification, and mixed samples are fine. Samples ship in 3–5 working days.

What is the lead time?
7–10 working days after deposit for standard bins; 1–2 weeks for large or customised orders.

Can the CCT or viewing angle be customised?
Six CCT ranges and three viewing angles are available from the same package. Custom bins and reel labelling can be arranged for volume orders.

What warranty applies?
2 years. Faulty units are replaced as described above.
