Reading Premium Lighting Model Numbers Like Spec Sheets
This brand does the unusual thing of publishing the specification
inside the product name, an EDI-LHB4FT-300W-xxK is a linear high bay,
four feet, 300W, color selectable, and the title finishes the job with
the efficacy and lumen figures, so comparing two units happens before a
single product page opens. The letters G1 through G5 mark generations of
the same fixture, later numbers bringing revised performance, which
means the generation is part of the decision, not decoration. The
deepest of these families competes on the store's main overhead shelf, high bay lights.
Linear and UFO High Bays, 165W to 500W
The linear high bays run two and four foot bodies from 165W up to the
400W and 500W G4 aluminum units, with title efficacies of 150 to 168
lumens per watt and outputs reaching 80,000 lumens on the largest model,
numbers that put whole warehouse aisles on single fixtures. The UFO
round bodies sit beside them, a 320W unit listing 51,000 lumens, for
jobs that prefer point sources over lines. Between the two shapes the
deciding inputs are mounting height, aisle geometry, and how the racking
shadows light, all resolved against each listing's photometrics rather
than the wattage alone.
The Sensor Base Ecosystem
Right at half the titles on this line mention a sensor or a sensor
base, AUX and 3-Pin receptacles built into the fixture body that accept a
plug-in occupancy or microwave sensor instead of hardwiring one, and
that one design choice is the brand's quiet superpower. A warehouse can
install fixtures bare today and snap sensors in next year when the
energy code or the utility rebate demands it, without lifts revisiting
every unit's wiring. Check which base each model carries, because AUX
and 3-Pin parts are not interchangeable, and the strip family in strip lights plays the same game in eight foot form with microwave options in the titles.
Color Selectable as the Default
The xxK and 35/40/50K endings on most models mean the color
temperature is chosen on the fixture at install among warm, neutral, and
cool settings, so one carton covers whichever tone the space
standardizes on. The backlit panels carry the same convention into grid
ceilings, 2x4 bodies listing 72W and 10,000 lumens for office and back
of house work, and the four foot vapor tights extend it into washdown
and parking areas at 60W. The sealed family as a whole lives under vapor tight fixtures for cross brand comparison.
Type B Tubes Mean Line Voltage in the Sockets
The tube side of the shelf includes eight foot FA8 single pin T8 LED
lamps at 40W marked Type B, and that marking is a wiring statement, not a
style: Type B tubes run on building voltage delivered straight to the
lamp sockets with the old ballast removed from the circuit. The payoff
is no ballast to ever replace, the price is a rewiring step that puts
the retrofit squarely in a licensed electrician's hands, with the
fixture relabeled per the tube's instructions. The full lamp range, Type
B and otherwise, stocks under tube lamps.
Building the Premium Lighting Order
Because the titles carry wattage, efficacy, output, generation, and
sensor readiness, a fixture schedule maps onto this shelf almost line
for line: match each space's mounting height and target light level to a
model, hold one generation per area for visual consistency, and count
sensor modules in the same pass so the bases do not sit empty. Wall
packs in up and down configurations at 120W cover the exterior entries,
and the whole package, interior to exterior, goes to the counter as one
list. Panels and grid ceiling work compare widest over in panel lights.
Premium Lighting Buying Questions
What do the G1 through G5 marks mean?
Generations of the same fixture design, with higher numbers being
newer revisions, and the titles show the performance moving between
them, a G5 linear high bay listing 168 lumens per watt against 160 on
earlier units. Match generations within one space so rows look and
measure identical.
What is the difference between an AUX and a 3-Pin sensor base?
Both are receptacles on the fixture that accept plug-in sensors, but
they are different connectors taking different modules. The title of
each fixture names which base it carries, so order sensors against that
name and never assume one warehouse's modules fit the next building's
fixtures.
Why does lumens per watt matter more than wattage?
Because it is the fixture's fuel economy. Two 300W high bays can
produce different light levels, and the 150 to 168 lumens per watt
figures in these titles say how much illumination each watt buys, which
is the number utility rebates and energy comparisons actually run on.
Can I put a Type B tube into a fixture without rewiring?
No. Type B operation requires the ballast removed and line voltage
wired to the sockets, done by a licensed electrician with the fixture
relabeled. Installing one into an unmodified ballast fixture is a
mismatch, so confirm the tube type and the fixture's wiring state before
the swap.
