Frequently Asked Questions

What is the main benefit of an LED HID retrofit?

The primary benefit is massive energy efficiency; these lamps consume up to 83% less energy than legacy systems while delivering identical or improved light levels.

Do these bulbs require a ballast bypass?

Yes. These are Type B lamps designed for easy ballast bypass, allowing the lamp to operate directly on line voltage (120-277V or 277-480V).

Can I adjust the light color after installation?

Many field-adjustable models feature a "Color Select" switch, allowing you to choose between 3000K, 4000K, or 5000K tones.

Will these fit in my existing enclosed fixture?

Yes, most Performance Class retrofits are rated for both open and enclosed fixtures and feature a reduced size (up to 30% smaller) to fit tight ANSI footprints.

How do smart sensors connect to the lamp?

Sensors often use a standard 3.5mm AUX port or a 3-pin "Smart Port" for instant controllability without additional wiring.
