LED Heavy Duty High Bay
The PBL G2 HD is a "heavy duty" high bay with high efficacy LED technology. Just like the PBL G2 LED high bay, the PBL G2 HD boasts efficacies up to 179.5 lumens per watt! Designed for areas where the luminaire may be struck, the housing is constructed of sturdy 0.063" aluminum. Wireguards can be purchased for added durability. The PBL G2 HD's unibody design is surface mountable, with easy access to the driver compartment from below. Pendant and cable mounting options are also available. There is a wide range of lumen outputs and several control options. Frosted diffusers are available to minimize glare and improve aesthetics. Every PBL G2 HD is made in the USA - in our Henderson, NC facility, utilizing mostly domestic and some foreign components.

Mounting options
The PBLHD G2 can be surface-mounted, cable-mounted or pendant-mounted. The 4-foot version is offered with a stabilizer option (pictured). For surface mounting, the center portion of the LED tray can easily be removed to access the mounting holes underneath (see spec sheet for more information). Cable kits come pre-looped for easy installation and are designed for easy fixture height adjustment.
