Commercial LED lighting retrofit
A retrofit swaps old fluorescent or HID lighting for LED. How it is done changes safety listings and rebates.

The short answer
A commercial LED lighting retrofit replaces fluorescent, metal halide or other lamps with LED, by new fixtures, listed retrofit kits, or LED tubes. A licensed electrical contractor handles ballast removal or bypass, controls and permits. Energy codes may require controls when many fixtures change, and utilities often offer rebates.
Three approaches
New fixtures: cleanest result. Retrofit kits: listed kits installed in existing housings. LED tubes: plug-and-play, ballast-bypass or hybrid. Ballast-bypass tubes involve rewiring sockets.
UL 8750 covers LED equipment; use listed products.
Controls and energy code
Large retrofits can trigger energy code requirements for occupancy sensors and daylight controls. DOE guidance covers LED savings.
Utility rebates
Many utilities offer rebates for qualified LED products. Check rules before buying; some require pre-approval.
Time and what changes the price
Phased work at night avoids disruption.
Price drivers: fixture count, ceiling height, approach chosen, controls, after-hours work. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Choosing a contractor
Ask about lift work, disposal of lamps and ballasts, and rebate paperwork. Check the license on your state board before anyone starts: how to check an electrician license.
Ballast-bypass tubes: what changes
Ballast-bypass LED tubes run on line voltage at the socket. The fixture is rewired, and it should be labeled so the next person does not install a fluorescent tube in it. Mixing tube types in one building makes maintenance harder.
Plug-and-play tubes keep the ballast, so they install fast, but a failed ballast still has to be replaced. Hybrid tubes can run either way.
New fixtures or listed retrofit kits avoid both issues and often allow better optics and controls. Ask the contractor to compare all three for your ceiling type and hours of use.
Measuring the result
Ask for light-level readings before and after in key spaces, and confirm the energy figures the rebate program uses. DOE guidance on LED lighting explains why LEDs use less energy and last longer than older lamps.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
