Lighting for Paint Booths — Explosion-Proof LED Solutions for Hazardous Locations
Inside the booth is Zone 1 (C1D1); the area just outside is Zone 2 (C1D2). Here's what the Canadian code requires, the fc targets that matter, and which LEDEX fixtures — SENTINEL (C1D1) and Vector (C1D2) — go where.
Why paint booths need explosion-proof lighting
Spray-finishing environments are hazardous locations, plain and simple. Ordinary LED fixtures — even bright, well-sealed ones — are not code-compliant inside or near a booth. The wrong fixture is an ignition source in a space engineered specifically to contain flammable atmospheres.
This guide covers what the Canadian code requires, what light levels you should target, and which LEDEX fixtures fit C1D1 (inside the booth) and C1D2 (just outside).
What the code says
The Canadian Electrical Code Section 20 (Rules 20-300 to 20-314) covers hazardous finishing operations. Under Rule 20-302, the following are Zone 1 (C1D1):
- The interior of spray booths and their exhaust ducts (with adequate ventilation)
- Any space within 6 m horizontally, and up to 1 m above the goods, of spraying done outside a booth
- Within 6 m of dip tanks and drain boards, up to 1 m above them
And Zone 2 (C1D2) applies:
- At least 1.5 m out from the open face of an open-face booth
- 1 m in all directions from openings in a closed booth or paint room
For the full breakdown of zones and what C1D1/C1D2 mean for equipment markings, see Zones 0/1/2 and 20/21/22 explained and EPL and T-codes.
Lighting targets that matter
Color matching and defect detection take a lot of light. Industry consensus sits in the 100–150 foot-candle range (≈1,100–1,600 lux) at the work plane.
Sizing table for a ~200 sq ft (~18.6 m²) booth:
| Target | Approx lux | Total lumens needed* |
|---|---|---|
| 100 fc | ~1,075 lux | ~45,000 lm |
| 120 fc | ~1,300 lux | ~54,000 lm |
| 150 fc | ~1,600 lux | ~65,000 lm |
*Assumes typical light-loss factors and a reasonable uniformity ratio.
For that booth, plan on roughly four linear fixtures in the 10,000–13,000 lm range each — wall-mounted at 45° if the booth has side windows, ceiling-mounted if not.
LEDEX fixtures for paint booths
Three options that together cover every zone in a typical paint shop. Pick by where in the booth the fixture is going.
SENTINEL Series — C1D1 linear (inside the booth)
Our flagship Class I Division 1 / Zone 1 linear, designed for inside spray booths and the immediate spray zone. Up to 17,000 lm, 170 lm/W efficacy, -40 °C to +65 °C operating range.
- Where it fits: inside the booth, exhaust plenum, dip-tank overheads
- Ratings: C1D1, C1D2, C2D1
- Optical: tempered glass lens, multiple beam options
- Install: 8.5 kg housing, screw-cap wiring access, toolless cage-clamp terminal block
Vector Series — C1D2 linear (outside the booth)
Our workhorse Class I Division 2 linear for the area just outside the booth — mixing rooms, parts staging, and egress paths within the hazardous envelope.
- Where it fits: within 1.5 m of an open-face booth, mixing/prep rooms, paint kitchens
- Ratings: C1D2, C2D1
- Install: continuous-run compatible, ceiling or wall mount, trunnion or swivel options
Vector with Emergency Battery Backup
Same Vector fixture with an integrated battery for egress lighting during power loss — often required where the spray area doubles as part of an exit path or the shop has no natural light.
- Where it fits: egress routes, booth-adjacent corridors
- Ratings: C1D2, C2D1
- Backup: integrated battery, continuous egress illumination during outage
Which fixture do I need?
| Where the fixture goes | Rating required | Use |
|---|---|---|
| Inside a spray booth | C1D1 (Zone 1) | SENTINEL |
| ≤ 1.5 m outside an open-face booth | C1D2 (Zone 2) | Vector |
| Mixing / prep room adjacent to booth | C1D2 (Zone 2) | Vector |
| Egress path, power-loss critical | C1D2 + emergency | Vector EM |

Canada runs two classification systems side by side: Zones (CEC default since 2015) and Class/Division (still allowed for existing facilities, and still on most spec sheets you'll see). Here's both, in plain English, with the CSA and NEC definitions.
