This site exists for one reason: to make the wattage unambiguous. For all six full-colour pure-laser models we list laser source power, fixture power, beam angle and aperture separately, exactly as they appear in the spec sheets — plus downloadable spec sheets and real field footage, so consultants and distributors can compare like with like.
Est. 2010 · Guangzhou, China · Full-colour pure-laser beam fixtures
Guangzhou Boyi Lighting Appliances Co., Ltd. (SOUTH LITE / BOYI LIGHTING) was founded in 2010 and is based in Panyu District, Guangzhou. We engineer RGB pure-laser sources into production fixtures for stage and outdoor lighting — colour-mixing optics, TIR homogenisation, prism effect wheels, pan/tilt scanning and thermal design are all developed and assembled in our own factory, exporting to Europe, Australia and Southeast Asia.
Two lines — moving-head beam lights and array laser searchlights — with laser source power from 230 W single-source up to 4-group 500 W arrays, covering theatre, touring, night-tourism and landmark projects.
All models RGB pure laser, no phosphor conversion.
OEM / ODM and voltage variants available; we size illuminance estimates and recommended power classes from your throw distance and target surface; English-speaking sales for export enquiries.
Measured 20 m / 50 m illuminance and photometric files available per model.

Same fixture, three different watts
A “500W laser light” is routinely compared against another “500W laser light” — yet one can be several times brighter. One number may be the laser source, another the whole fixture, and a third an equivalent output of a phosphor-converted design. Align the definition first; only then does a comparison mean anything.
Combined electrical input power of the red, green and blue laser diodes after colour mixing. It sets the ceiling on how far and how hard the beam can throw — the rating we publish, and the definition that travels across brands.
Every “230W / 4-group 500W” figure on this site is laser source power — not fixture power, and not optical output.
Laser source power plus drivers, cooling, pan/tilt and control. This is the number that sizes distro, cable runs and generators — the one rental companies and outdoor projects budget against.
Fixture powers across the line: 350 / 600 / 700 / 1200 / 1850 / 2500 W. The number in a model name is not the wattage.
The same wattage through a different aperture and beam angle can differ by an order of magnitude on the wall. Tenders and commissioning are judged on lux at distance, never on watts.
Measured 20 m / 50 m illuminance and photometric files are available on request for all six models.

Laser source power is the electrical input to the laser source (industry convention rates by electrical power), not optical output; fixture power includes drivers, cooling and pan/tilt control. SL-3500PRO / SL-4500PRO are multi-source fixtures rated per group — totals are not summed. Figures are taken from the product spec sheets and are subject to measured reports and contractual technical agreements.
