Commercial Light Bulb, Tube and Ballast Replacement
Commercial relamping means replacing failed bulbs, tubes and lamp parts across a building in one visit instead of one fixture at a time. It covers fluorescent tubes, LED tubes and bulbs, screw-in lamps, exit-sign lamps and emergency-light batteries. A tidy relamp restores lighting levels, removes flicker and stops the dark patches that make corridors and stairwells feel unsafe.

Most lighting problems are small and the cause is quick to find. A tube that flickers or has dark ends has reached the end of its life. A fixture that stays dark with a good tube often has a failed ballast or driver. Checking those two items before swapping bulbs for the third time saves a lot of repeat visits.
Some work sits on the line between maintenance and electrical trade work. Swapping a bulb is routine, while rewiring a fixture, converting a fluorescent fixture to LED line voltage or working on a panel is normally for a licensed electrician in most places. A good handyman quote says which side each item is on.
What the work includes
- Walking the building to list dead, flickering and dim lamps
- Replacing fluorescent tubes, LED tubes, compact lamps and screw-in bulbs
- Checking and replacing starters or plug-in ballasts where the fixture allows
- Replacing failed diffusers, lenses and lamp holders that snap in
- Swapping exit-sign lamps and emergency-light batteries
- Matching colour temperature so rooms do not end up with mixed light
- Working from ladders or lifts in tall spaces such as lobbies and atriums
- Removing old lamps and boxing them for recycling where required
Clues that it is time to relamp
Flickering or humming tubes in an office, corridor or washroom
Dark ends or yellow-brown staining at the end of fluorescent tubes
Mixed bright and dim fixtures in the same room
Fixtures that stay dark even after a new tube goes in
Exit signs or emergency lights that no longer light or hold a charge
Tenants reporting dim parking areas, stairwells or loading docks
How the work goes, step by step
Send the list
Note the locations of failed lights, the lamp types if you know them, and photos of any labels.
Check and plan
Tube length, base type and ballast style are confirmed, and any fixtures needing an electrician are flagged.
Written quote
The quote lists each area, lamp type, quantity and what is included, with licensed-trade items called out separately.
Replace and test
Lamps are changed, each fixture is tested and any that still fail are noted with the likely cause.
Summary
You receive a list of what was changed and what needs further attention, with photos if requested.
What changes the price
- Number of fixtures
- A bulk relamp is cheaper per lamp than a single-bulb visit because the walk and setup are shared.
- Ceiling height
- Anything beyond a stepladder needs a platform or lift, which slows each change.
- Lamp type
- LED tubes cost more than fluorescent ones up front, and specialty or obsolete bulbs are priced separately.
- Ballast or driver failure
- A fixture that needs a new ballast takes more time and may be flagged for an electrician.
- Access and hours
- Occupied offices, locked rooms and after-hours work add time and coordination.
- Disposal
- Fluorescent tubes contain mercury, and recycling them can carry a handling charge.
What a good quote spells out
- Lamp type and colour temperature stated, so replacements match what is already there
- A clear statement on who handles ballasts, drivers and LED conversions
- Who supplies the lamps and how spare stock is handled
- Whether lift or ladder access is included for high ceilings
- How old lamps are recycled and whether disposal is itemised
Bulb & Ballast Relamping: questions people ask
Can a tube be replaced without turning off power?
Many tenants do swap tubes themselves, but the safest approach is to switch off the fixture and let it cool. Professional crews follow site rules and use proper access equipment, especially above ceilings or on lifts.
Should we switch to LED while relamping?
LED tubes can cut energy use and cut maintenance, but some types need the ballast removed or rewired. That is electrical work in most places, so ask whether a plug-and-play type or an electrician-supplied conversion fits your fixtures.
Why does a new tube still not light?
The fixture may have a failed starter, ballast, driver or lamp holder. Testing with a known-good lamp points to the cause, and a ballast change may need a licensed electrician depending on local rules.
How often should lights be changed?
Fluorescent tubes dim before they fail, so a building-wide relamp every few years keeps light levels even. LED lamps last much longer, and failures are usually spot repairs.
