Interior of a large distribution warehouse lit by rows of LED high bay fixtures

Commercial & Industrial Lighting Supply

Fixtures, drivers, ballasts, lamps and emergency lighting for electrical contractors, facility managers and maintenance buyers.

Multi-storey parking structure lit at night

Size the fixture before you shop it

Wall packs, area lights and floods split by lumen output, mounting and cutoff - so you can match the spec instead of scrolling past it.

Commercial interior lit by suspended drum pendants over a meeting table

Emergency drivers on the shelf, not on order

Bodine, IOTA and Keystone stocked, because an exit sign failing inspection is not a lead-time problem.

We are your lighting experts

LED Drivers & Emergency Backup

Constant current, constant voltage, dimmable and 0-10V drivers, plus the deepest emergency driver inventory you will find online — Bodine, IOTA and Keystone, stocked rather than ordered in. Still carrying fluorescent and HID ballasts for the buildings that have not converted yet.

Why BulbsDepot

Lighting experts, not just lighting suppliers
Our portfolio of lighting projects shows what we can do in lighting design. If you need a partner to help transform your space, we are here for you.
Fast shipping
93% of our orders ship within one business day, and 94% within two.
Largest Philips distributor in the Midwest
Philips lamps, Advance ballasts and Bodine emergency drivers stocked in depth, not treated as an accessory to order in.
Legacy parts nobody else keeps
CFL plug-ins, metal halide, T12 ballasts and HPS still on the shelf. A discontinued ballast rarely swaps one for one - the replacement usually changes ballast factor or start method, which shows up as light level and lamp life, not as a fitting problem.
Lighting logistics for national accounts
We have the expertise to deliver lighting products efficiently to companies around the world. We have even delivered Philips lamps to Philips in China.
Commercial accounts and net terms
Apply once and order against terms - set up for maintenance and property management teams and contractors buying the same parts across a portfolio of buildings.

Lighting services

The parts are half of it - we also price the job, lay it out, and bring it back under budget when the number comes in high.

Quotations
Send a plan set, a fixture schedule, or a photo of what is up there now, and we price it, including the substitutions that still hold the spec.
Lighting layout
Photometric layouts with fixture counts, mounting heights and spacing - a lot can hit its average foot-candle target and still fail on uniformity, and the layout is where you find that out.
Value engineering
When a package comes in over budget we re-specify to the same light levels at a lower cost, rather than cutting fixtures out of the count.
White Design Studio
For branded and architectural work we team with White Design Studio, an independent design practice, on the design side of the package.

Featured projects

BulbsDepot White Design Studio brand experiences

Showrooms, lobbies and customer experience centres, lit to a design. White Design Studio do the branding, architecture and environmental graphics; we work the lighting alongside them. Design and photography below are theirs.

  • Flooring showroom with track lighting across an exposed black ceiling and illuminated sample displays

    Thornton Flooring + Design Center

    Sioux Falls, SD

    An empty lot to a first-class flooring showroom. Track runs the length of an exposed black ceiling, with every sample display lit to be read at a glance.

    Design and photography: White Design Studio

  • Exhibit hall with spotlit searchlights on plinths, a backlit landscape mural and track lighting on an exposed black ceiling

    Carlisle & Finch

    Cincinnati, OH

    A customer experience centre for 125 years of searchlight manufacturing. Track and accent lighting pick the products out of a dark room without flattening the backlit mural behind them.

  • Circular briefing room with a cove-lit ceiling ring above a round table and a curved video wall

    University of Phoenix

    Phoenix, AZ

    A briefing room lit as part of the exhibit rather than around it - a cove ring above the table, held low enough that the video wall still reads.

  • Office lobby timeline wall connected by tubes of light, with an illuminated display case

    HORAN

    Cincinnati, OH

    A lobby timeline connected by tubes of light, and a company history lit from inside the objects themselves.

    Design and photography: White Design Studio

  • Office lobby with recessed ceiling lighting, seating and a wall-mounted company logo

    North American Properties

    Cincinnati, OH

    Three floors of lobby and conference space relit as part of an interior and experiential design update.

    Design and photography: White Design Studio

  • Office break area with pendant lighting over tables and a wall-length illustrated graphic

    Procter & Gamble, HR and PSO

    Cincinnati, OH

    A brand experience package across whole floors, where the environmental graphics double as wayfinding and the lighting has to keep both legible.

Retrofits and upgrades

Our own work - existing buildings taken to LED, specified, supplied and seen through.

  • Historic hotel facade at night, ornamental stone pilasters lit from below by warm grazing uplights

    TownePlace Suites

    Grazing uplight on a historic facade, picking out the terracotta detail after dark without washing the guest rooms above it. The uplight is a fixture we import directly - it is not sold through US distribution.

  • School corridor lit by recessed linear LED, lockers along both walls

    Mariemont City Schools, lighting retrofit

    Village of Mariemont, OH

    A district-wide retrofit to LED, corridors and classrooms.

    Illustrative image, not a photograph of this installation.

  • Decorative LED post top lanterns lit at dusk along a village path, with a stone church and planted borders behind

    Mariemont post top retrofit

    Village of Mariemont, OH

    Village street lighting retrofitted to LED post tops - warm, low glare, and photographed at the hour that actually shows what it does.

Philips, Advance, Bodine, Halo and Metalux all sit under one manufacturer.

Commercial and industrial lighting supply.

BulbsDepot supplies lighting to electrical contractors, facility managers and maintenance buyers nationwide - indoor and outdoor fixtures, LED drivers and ballasts, lamps, controls and emergency lighting. Whether you are lighting a new building, retrofitting metal halide to LED, or replacing a fixture discontinued six years ago, we stock what the job needs. Where the job still needs designing, we do that part too.

We quote from plan sets, produce photometric layouts, and value engineer a package that comes back over budget without taking the quality out. On branded and architectural work we team with White Design Studio. That work has covered hotels across four Marriott and Hilton brands, showrooms, offices and historic facades - exterior through egress, new construction and PIP renovation.

Our range covers outdoor lighting - wall packs, flood lights, area and parking lot lighting, bollards and canopy - alongside commercial indoor, high bay, troffers and flat panels, and a full emergency and exit range. We carry RAB, Westgate, Keystone, Philips Advance, Satco, Sylvania, Cooper Metalux, Halo and LSI, plus exterior product we import directly because it is not available through US distribution.

We are the largest Philips distributor in the Midwest, with deep emergency driver and ballast inventory across Bodine, IOTA and Keystone, and we still stock the legacy lamps and ballasts most suppliers dropped: CFL plug-ins, metal halide, T12 and HPS. A discontinued ballast rarely swaps one for one. The replacement often changes ballast factor or start method, and that shows up as light level and lamp life, not as a fitting problem.

Commercial accounts order against net terms, which suits maintenance and property management teams repeating an order across a portfolio of buildings, and national accounts get the logistics to match - lighting delivered to sites across the country and around the world. And someone on the phone knows what a T12 ballast is.
