The Light Source, WL Series LED House Light


The ultimate LED House light providing high quality white with excellent dimming, tight beam control, and supports applications requiring up to 10,674 lumens.



The Light Source WL Series 6” Fresnel LED House Light is perfect for applications requiring up to 10,674 lumens, excellent dimming, tight beam control, and high quality of white light. The luminaire provides a look and feel of natural, single source incandescent light, as well as excellent LED performance and longevity. It is the ideal choice for atriums, auditoriums, churches, hotels, museums, schools, studios, theaters, and similar venues.


The LED driver has a universal input range of 100VAC – 277VAC 50/60HZ with no adjustments required. Also a mean time between failures of 330,000 hours. The 150 Watt LED driver may be factory preset to 80, 100, 120, or 150 Watts. The LED driver has active power factor correction with 99% PF at 120VAC, ATHD of 7%, and draws only .84 Amps. There is an inrush current limit, allowing up to 12 of the 100 watt LED fixtures to run on a single pole 20 Amp 120VAC circuit breaker.

The LED House Light responds quickly, producing full light output in 2-3 seconds after power is applied. Does not require relays to turn the fixtures off between uses. Fixtures have a full rating for 24/7/365 operation. Also, this enables instant response to DMX control signals without waiting for relays to sequence and fixture boot time. Standby wattage is less than 1 Watt with power on and DMX at level 0. Annual quiescent power draw is less than 9 KWH.


In addition, power connections may be hardwired internally with a rigid conduit connection and the provided flip lever Wago connectors, or externally with a 72” 18/3 SJOwire whip, or connected to an optional external flush Neutrik PowerCon connector. DMX data connections may be hardwired with the provided IDC or screw terminal plugin connectors; or the optional external flush mounted Neutrik 5 pin XLR; 3 pin XLR; or RJ-45 Ethercon connectors.


The Light Source, Inc. WL Series fixtures are fully DMX dimmable with extremely smooth 24 bit dimming utilizing only single channel DMX dimming control. The dimmer microprocessor is able to use over 16 million steps from full intensity to off for incredibly smooth dimming. There is no flicker on video with either line scan or global camera shutters interacting with the 30khz output frequency. The DMX line is fully isolated to 2500 Volts per microsecond.

Users can enable the Light Source proprietary Thermal Mass Equivalence during installation by turning dip switch 1 to off. Also, this setting allows the DMX control channel 512 to change the dimming performance to emulate a large or small incandescent lamp, or to change the dimming performance to an instant response. The fixture is also available in a non-dimming version.


Based on Cree’s product testing, the WL Series fixture’s standard LED module offers over 100,000 hours of life operating from 80 – 150 input Watts. Individual LEDs operate close to half of their maximum drive current even when the fixture is at 150 Watts. Low drive current increases the LED brightness and life. The 60 individual LEDs are carefully factory selected to maintain minimal color variance between LED modules.

The white LEDs are available in color temperatures of: 2700K, 3000K, 3500K, 4000K, and 5000K. The standard LED module has a typical CRI of 82. The LED module is factory built on a copper PCB for maximum thermal and optical performance. Every LED module is tested by thermal imaging to verify all electrical and thermal bonding connections. LED color bins used in each LED module are recorded with the fixture serial number. No appreciable IR or UV is produced by the LED module. Extreme heat and cold ambient temperatures do not adversely affect the LED output. The LED module is replaceable utilizing normal hand tools.


Optical systems come with 65 degree lenses and LED House Light Glare Shields installed. Sixty tightly clustered Cree LEDs and a 6” tempered borosilicate Fresnel lens combine to provide a single source look that completely emulates an incandescent source. Similarly, efficient use of the lumens generated by the LED cluster is accomplished by directing the LED output to the task area. Further, the fixture utilizes an additional condenser lens to maximize the lumen output on the 52° and tighter beam spreads.


The maximum ambient operating temperature is 122° Fahrenheit, (50° C). With no fans or other devices to generate noise, the fixture is completely silent in operation. A passive, convection cooled aluminum composite heat sink has plenty of space between fins to maximize the heat exchange and air flow. Also, the short direct thermal path to the large convective surface area of the heat fins keeps the 60 Cree LEDs to a delta of 25° C above the ambient temperature.

The solid copper PCB has thermal bonds to a massive aluminum core with 85 W/mK thermal interface material. This thermal junction actually improves over time and has 10 x the efficiency of most commonly used thermal interface materials. Further, the entire thermal system works together to keep operating temperature very low, producing significantly higher LED brightness and longer life.


Additionally, users can mount the LED House Light’s yoke in several ways.
A 3/8” or ½” fastener or threaded rod, a Mega-Clamp, or a Purlin Clamp are mounting options.


The extruded aluminum LED fixture comes in a standard black anodized finish.
