The Larson Electronics GAU-48-320W-LED-DIMM Dimmable General Use High Bay LED Light Fixture is a 4` linear integrated LED light fixture that provides 38,400 lumens of illumination. This low profile, highly efficient LED light fixture is a direct replacement for existing four lamp T5HO fixtures, providing twice the lamp life, increased durability, and less energy consumption. 0-10V dimming combined with The energy efficiency and longevity of LEDs make this light option ideal for use in places requiring high bay illumination, such as warehouses, malls, parking garages, and other similar environments.
The GAU-48-320W-LED-DIMM integrated 320 Watt LED light fixture is a low profile linear light fixture that provides 38,400 lumens of bright light in a 160° wide flood beam spread. Special heat dissipating design in conjunction with LED technology helps this fixture to achieve an excellent 60,000 hour rated lifespan with 80% lumen retention. The GAU-48-320W-LED-DIMM is housed in aluminum casing and the LED assembly is protected by a shatter resistant polycarbonate lens. This unit is multi voltage, operating on 110-277 AC 50/60 Hz, and supplied with a 10` line-in cable with flying leads. We also offer a low voltage 12-24V AC/DC model for low voltage applications, such as off the grid and remote locations powered by alternative energy.
The GAU-48-320W-LED-DIMM offers 0-10V dimming. With 0-10V dimming, the supply fixture is equipped with a secondary low voltage dimming cable to control the light intensity of the fixture. This secondary signal cable is connected to the user provided dimming controls to dim the light fixtures. 0-10V dimming provides ten points of light intensity, with 100% light output at 10V and 0% light output at 0V. LED light fixtures capable of 0-10V dimming are compatible with Mark 10 style dimmer switches.
LED Drivers:
Even in LED fixtures, heat is the single largest factor in premature light failure and color shifting. As a result, many manufacturers reduce the output of their LEDs in order to reduce the amount of heat produced. Rather than lower light output or quality, Larson Electronics addresses this problem with the addition of an electronic LED driver. This internal driver provides the ability to automatically monitor and adjust input current to maintain the correct LED voltage levels regardless of input levels across a specific range. This not only reduces the energy dissipation, effectively lowering the operating temperature of the fixture, but also prevents AC over-voltage and short circuit loading making this fixture virtually maintenance free. Because the electronic driver allows the GAU-48-320W-LED-DIMM to run at a cooler internal temperature and regulates the electrical current, energy efficiency and LED service hours are maximized while at the same time reducing operating costs and downtime incurred from the frequent servicing intervals required with other hotter running lights.
The integrated heat sink allows for efficient heat dissipation, preventing the LEDs from overheating and keeping the overall temperature of the fixture relatively low. Solid state LED technology eliminates the need for a ballast box and lamps, a cumbersome feature of fluorescent fixtures that add weight and require frequent repairs. This low profile light fixture features two adjustable brackets, providing operators with easy installation and allowing for adjustments of the light assembly.
This unit is designed to be either surface mounted or hung from cable or chain and includes built in mounts. The GAU-48-320W-LED-DIMM light fixture is ideal for indoor-outdoor applications and suitable for use as general area lighting, shop lighting, work space lighting, garage and warehouse lighting, and anywhere a dependable and low maintenance fixture with high output and efficiency is needed. This light comes with a multi-purpose mounting bracket that can be used for a direct surface mount or reversed and used for chain hanging the unit.
