Common Questions About LED Retrofits

How is an LED retrofit different from a full fixture replacement?

An LED retrofit involves installing new LED components (like kits, tubes, or lamps) into your existing lighting fixture's housing. A full replacement means removing the entire old fixture and installing a brand new one.

  • Retrofit Advantage: Much faster installation, significantly lower upfront cost, and less material waste.
  • Replacement Advantage: Sometimes offers the latest in optical efficiency and a completely new warranty. Retrofits are the ideal cost-effective solution for most upgrade projects.

Can I really retrofit my old HID (metal halide) fixture with an LED kit?

Yes! HID retrofit kits are one of the most popular and cost-effective upgrades. They are designed to fit into the existing socket and housing of high bay, parking lot, and wall pack fixtures. The benefits are dramatic: instant-on light, no warm-up time, significant energy savings (often 50% or more), and a much longer lifespan.

Will retrofitting my lighting void the original fixture's UL listing?

This is an important consideration. When you modify a fixture with a retrofit kit, the original UL listing may be affected. However, if you use a UL Listed retrofit kit and install it according to the manufacturer's instructions, the assembly can maintain its compliance. Always look for retrofit products that are themselves UL Listed for safety and peace of mind.

How difficult is the installation process?

Many retrofit bulbs and kits are designed for a simple, "plug-and-play" installation that a qualified electrician can complete quickly. Kits often come with detailed instructions and mounting hardware. However, because some retrofits require rewiring (bypassing a ballast), we always recommend installation by a licensed electrician to ensure safety and compliance with electrical codes.
