50W LED Flood Light
The 50W LED flood light is the entry point of commercial flood lighting, and the wattage most often over-specified. At 3-6 m mounting - wall brackets, gate posts, low poles, sign gantries - it lights entrances, facades, pathways and small forecourts with better control than a larger fixture, which at that height mostly produces glare and spill.
Five SJTG housings carry a 50W variant, all die-cast aluminum and IP65-sealed. They ship with the same photometric files and documentation set as the high-power range, because a fifty-watt fixture on a building face still has to prove where its light lands.
Every Measured Unit, Published
All units tested on a calibrated HPG1800 goniophotometer. We publish the strong results and the modest ones — the economy build reads lower than the flagship, and both numbers are real.
Where 50W Fits
Selection guidance by mounting height and surface - confirmed with a free lighting layout.
3-6 m is the 50W envelope: wall brackets, gate posts, low poles and sign gantries. Above 6 m the output thins; step to 100W.
Narrow beams graze facades and frame signage; wide beams cover forecourts and pathways. The distribution decides the result at this rating more than the wattage does.
Entrances, gatehouses, building facades, signage, pathways, small forecourts, perimeter accents, loading doors.
For a yard, car park or working bay, move to 100W. Several 50W units still beat one large fixture where even coverage matters more than reach.

Where This Class Works
Three duties this wattage is specified for most often — and what changes in the specification for each.
Entrances, gates and access areas
At 3-6 m the 50W class lights the places people actually walk and drive through: gatehouses, doorways, ramps and short access roads. It is the wattage where getting the aim right matters more than getting more lumens, because the surfaces are close and glare is at eye level.
- 3-6 m mounting on walls and low poles
- Steep aim keeps glare out of eye level
- Photocell-ready for dusk-to-dawn duty
Facades, signage and building faces
Architectural and sign lighting is a precision job at modest output. Narrow beams graze a facade or frame a sign without washing the sky above it, and the fixture body stays small enough not to become part of the elevation.
- Narrow beam options for facade grazing
- Compact bodies stay visually discreet
- Controlled spill for dark-sky compliance
Pathways, forecourts and small yards
Where a site needs light every twenty metres rather than a floodlit expanse, several 50W units beat one large fixture: more even coverage, lower pole loads, and a failure that takes out one pool of light rather than the whole area.
- Even coverage from multiple small units
- One failure does not darken the site
- Lower pole and bracket loading

Straight Answers to the Questions Buyers Ask in Forums
What buyers report in sourcing forums and marketplace reviews — and how to check any supplier, including us.
Buyers routinely order 100W or 200W for jobs a 50W fixture lights better. Above about 6 m mounting a small fixture thins out, but below it a larger one simply produces glare and spill. Match the wattage to the mounting height and the surface, not to the budget.
50W is where the cheapest listings cluster, and where corners get cut on the gasket, the gland and the driver. Ask for the IP test evidence, the surge rating and the housing material before comparing prices - a die-cast body and a sealed driver cost more for reasons that show up in year two.
A narrow beam at 50W frames a sign cleanly; a wide beam at 100W washes the wall and the sky and annoys the neighbours. Specify the distribution for the surface you are lighting and the wattage usually comes down, not up.
IP65 means dust-tight and protected against water jets, which is the floor for permanently mounted outdoor fixtures. Fittings described only as weather-resistant or splash-proof are a different and lower claim - check for the rating and how it was tested.
50W LED Flood Light — Answered
What does a 50W LED flood light replace?
Typically a 150W metal halide or a 300-500W halogen flood. The replacement holds because directional LED optics put light on the target surface rather than scattering it, and because LED output does not collapse between relamping cycles the way discharge and halogen sources do.
Is 50W bright enough for a driveway or a building face?
For most driveways, entrances and building faces at 3-6 m mounting, yes - and often with better control than a larger fixture, which at that height produces glare and spill rather than useful light. The deciding factor is beam angle and aim, not wattage. Send the dimensions and we return a layout that shows the levels before you order.
Which 50W housing should I choose?
SJTG601 is the compact reflector body for tight brackets; SJTG603 adds toughened glass for impact-exposed positions; SJTG602 separates the driver cavity for hot climates; SJTG604 and SJTG606 suit projects that may scale to higher wattages on the same family styling. All five are die-cast aluminum and IP65.
Can 50W flood lights be used in multiples for a small court?
Yes, and it is often the better answer. Several 50W units give more even coverage and finer aiming control than one large fixture, with lower pole loading and no single point of failure. For a court that must hold a lighting class, the fixture count comes from the photometric calculation - we prepare it free from your dimensions.
