RAB YBLEDH Field-Adjustable Yardblaster Dusk to Dawn LED Area Light — 120W Selectable — 3000K/4000K/5000K — Wall or Arm/Pole Mount — Gray

The RAB YBLEDH Field-Adjustable Yardblaster pairs an integrated dusk-to-dawn photocell with wall or existing arm/pole mounting for outdoor area lighting. The photocell ships off by default, making its on/off setting an important part of configuring dusk-to-dawn operation. This Gray fixture ships set to 120W and 4000K, delivering 17,328 lm at that combination. Select 100W or 80W for lower output, and choose 3000K/4000K/5000K to set the light's color temperature. It operates on 120–277V, supports 0–10V dimming down to 10%, and carries UL wet-location, IP65, and DLC Premium designations.

Performance & Light Output

The 120W setting provides the highest output, while 100W and 80W reduce output in steps. Color temperature also changes the lumen, efficacy, and CRI values, so compare the complete wattage/CCT combination when selecting a setting.

At 120W: 15,816 lm (3000K / 132.5 lm/W / CRI 82); 17,328 lm (4000K / 150.5 lm/W / CRI 84); and 16,633 lm (5000K / 140.1 lm/W / CRI 83).

At 100W: 13,906 lm (3000K / 136.1 lm/W / CRI 82); 15,413 lm (4000K / 157.3 lm/W / CRI 85); and 14,759 lm (5000K / 145.2 lm/W / CRI 84).

At 80W: 11,422 lm (3000K / 140.1 lm/W / CRI 82); 12,798 lm (4000K / 163.1 lm/W / CRI 85); and 12,083 lm (5000K / 149.2 lm/W / CRI 84).

LED lifespan is 100,000 hours, based on IES LM-80 results and TM-21 calculations. RAB luminaires and LED components are independently tested in accordance with IESNA LM-79 and LM-80. Values are typical, with a ±10% tolerance.

Dusk-to-Dawn Control

The standard YBLEDH includes a 120–277V integrated dusk-to-dawn photocell with an adjustable on/off setting. It ships with that function off; select the photocell setting appropriate to the intended operation. Power and CCT adjustments set the light output and color temperature separately from photocell operation.

The optional twistlock-photocell configuration is identified by the /PCT ordering suffix. It is not the standard integrated-photocell configuration listed here.

Electrical

A constant-current Class 1 driver accepts 120–277V, 50/60 Hz input. Power factor at 120V is 99.8% at 120W, 99.7% at 100W, and 99.6% at 80W; at 277V it is 96.3% for each setting. THD at the 120W and 100W settings is 3.1% at 120V and 6.00% at 277V. Surge protection is 6kV.

The driver includes control wiring for 0–10V dimming down to 10%. Dimming requires a separate 0–10V DC dimming circuit.

Operating current across the three power settings:

Construction

Housing: Precision die-cast aluminum housing and arm.

Lens & Reflector: A polycarbonate lens and polyethylene terephthalate reflector form the optical assembly. BUG ratings are B3 U3 G2 at 120W and 100W, and B3 U3 G1 at 80W.

Finish: Gray, with a finish formulated for durability and long-lasting color.

Outdoor Suitability: UL wet-location listed with IP65 ingress protection. Minimum starting temperature is −40°F (−40°C), and maximum ambient temperature is 104°F (40°C).

Weight: The YBLEDH weighs 4.7 lb.

Installation & Mounting

Mounting Options: Install on a wall or existing arm/pole using 1 5/8-inch diameter pipe. Select the mounting configuration for the installation rather than assuming this fixture is wall-only.

Optional Mounting Arm: YARM24, sold separately, is the arm identified for the mounting arrangement.

Configuration: Factory settings are 120W, 4000K, and photocell off. Dimming requires a separate 0–10V DC circuit.
