Tired of swapping burnt-out PL tubes every year? The LIGHT EFFICIENT DESIGN LED-7312-40K-G2 is a GX23-2 LED retrofit lamp that drops straight into your existing 2-pin compact fluorescent fixtures — no new housing, no rewiring, no demolition. People look for it under many names: PL LED retrofit, 2-pin PL lamp replacement, CFL to LED conversion bulb, GX23-2 plug-in LED, or simply a 13W CFL replacement. It is built for fixtures where the lamp sits sideways, which is why it carries a horizontal mounting orientation: wall sconces, stairwell fixtures, small recessed cans, vanity lights, exit corridors and decorative pendants that have run on pin-base fluorescent lamps for years.

This one is the 4000K version, a neutral white that reads clean and alert without turning blue — exactly what people mean when they search for a 4000K LED bulb for an office, a school or a shop. It pulls only 7W and delivers 880 lumens, replacing a 13W 2-pin compact fluorescent lamp while keeping light levels where you want them. Colour rendering is 80+ CRI, so skin tones, signage and merchandise still look right. The lamp runs on 120-277V and also works on 208V and 240V, so one part number covers residential, commercial and mixed-voltage buildings. Rated life is 50,000 hours (L70), it operates from -40°F to 104°F, it is suitable for damp environments, it resists insects and dust, and it can be used in semi-enclosed recessed fixtures. Body length is 5.7" with a 1.3" width.

Where does it shine? Condo corridors, stairwells and lobbies, school washrooms, clinic hallways, hotel rooms, retail displays, garages and workshop task lights — anywhere a Canadian building still has pin-base fluorescent lamps and a maintenance crew tired of ladders. It fits fixtures using the GX23-2 two-pin base; if your fixture uses a different base, look at the 7W G23-2 retrofit 4000K or the omni-directional 5W GX23 retrofit 4000K. Prefer a warmer light in the same body? See the 7W GX23-2 retrofit 3500K. Order the SKU LED-7312-40K-G2 and cut your lamp changes down to almost nothing.

Built to slide into fixtures you already own
The LED-7312-40K-G2 belongs to the Light Efficient Design pin-base retrofit family that replaces Type A/B 2-pin PL lamps. The concept is simple: keep the luminaire, keep the trim, keep the wiring, change only the lamp. The body measures 5.7" long by 1.3" wide, close to the footprint of the compact fluorescent tube it replaces, so it clears most sconce glass, stairwell lenses and small recessed housings. It is engineered for horizontal mounting orientation, meaning the optics and the heat sink are laid out for fixtures where the lamp runs sideways — the most common configuration in wall-mounted and shallow ceiling fixtures.

Light quality that actually helps people work
At 4000K you get a neutral white that keeps corridors, washrooms and workstations looking crisp and awake without the clinical edge of a 5000K daylight tone. With 80+ CRI, colours stay honest: paint, uniforms, packaging and printed signage all read the way they should. The lamp produces 880 lumens from only 7 watts while replacing a 13W 2-pin CFL, and unlike fluorescent it starts instantly at full brightness — no warm-up, no flicker, no dimming over the first minute in a cold stairwell.

Installation, voltage and compatibility
Because it accepts 120-277V and also works on 208V and 240V, the same lamp can be deployed across a building where corridors run at 120V and mechanical rooms at 277V, which removes a lot of guesswork from a retrofit order. Confirm the base on your existing lamp before ordering — this model is GX23-2 only. The family also covers G23-2 at 4000K, GX23 omni-directional at 5W, and if you want to set the tone on site there is the GX23-2 Flex Color 3000K/3500K/4000K version with selectable colour temperatures. The rated 50,000-hour life and the -40°F to 104°F operating range make it a sound choice for unheated stairwells, parking entrances and vestibules across Canada.

Real projects and documentation
Think of a property manager with two hundred wall sconces in a condo tower, a school board replacing washroom and hallway lamps over a summer, a clinic that wants consistent neutral light room to room, or a small business owner refreshing a retail entrance without calling in an electrician for a full fixture swap. In each case the payback comes from the same place: fewer watts, fewer ladder trips, and a PL LED retrofit that keeps the original fixture design intact.
