Overview

Diode Dynamics SS40 Pro LED Standard Light Bars

Diode Dynamics SS40 Pro standard light bars are 40 in. off-road auxiliary lights featuring patented TIR (Total Internal Reflection) optics and high-intensity LEDs. The "Pro" designates a higher power output tier, while the "Standard" refers to the built-in amber backlight without a startup sequence.

Key features:

* Optics and output: Unlike traditional reflectors, the TIR lenses capture and focus nearly all the light, shining it precisely where needed to eliminate wasted light and glare
* Power levels: The Pro series pushes noticeably more power and higher lumens compared to entry-level Sport models
* Backlight: Standard models include a built-in amber-only accent backlight that illuminates the entire optic
* Durability: Built to withstand the elements with a rugged aluminum housing, an ASTM-certified powdercoat finish, and a high-grade IP69K waterproof rating
* Available beam patterns: The SS40 is highly adaptable and available in different beam patterns depending on your driving needs:
-- SAE Driving: Balances reach and width (20x12 degree spread) for general illumination and supplementing high beams
-- Spot: A highly focused 8x8 degree long-distance beam, ideal for seeing far ahead at high speeds
-- Flood: Provides smooth, even, wide-angle illumination (100x80 degrees) for low-speed maneuvering, campsites, or work areas
-- Combo: Some versions mix spot and driving/flood optics in different segments of the same bar for both distance and foreground coverage
