LED High Bay Lighting for Metal Warehouse: 150W LED Retrofit in Israel

Project Location: Israel
Application: Metal Storage Warehouse
Replaced Fixture: 400W HPS Lamps
New Fixture: 150W LED UFO High Bay (HBS Series)
Brand: SEEKINGLED

This project took place in a metal storage warehouse where lighting had never been questioned—until maintenance became a recurring issue.

The warehouse had been operating with 400W HPS lamps for years. They worked, in the sense that light came on. But failures were frequent enough that replacement schedules started to overlap. Accessing the fixtures meant stopping certain operations, moving equipment, and coordinating lift work. That cost was not always written down, but everyone felt it.

The initial request was simple: reduce lamp replacement and energy load without changing the layout.

Site Conditions

Ceiling height was consistent across the warehouse. The space was open, with heavy metal materials stored on racks and pallets. Dust was present, but not extreme. Heat buildup near the ceiling was more noticeable, especially during long operating hours.

The HPS lamps produced uneven light across aisles. Some areas felt bright directly under fixtures, while side zones dropped off quickly. Color shift over time made inspection work harder, especially when identifying surface conditions on metal stock.

Fixture Selection

We selected the 150W LED UFO high bay from the HBS Series as a direct replacement for the existing 400W HPS lamps.

The decision was not based on wattage comparison alone. Heat management mattered. The aluminum housing and passive cooling structure were considered early, because this warehouse runs long hours with limited shutdown periods.

MEANWELL drivers were specified from the start. In environments like this, driver stability over time matters more than chasing higher output numbers.

Neutral white was chosen. It gave enough clarity for material handling without pushing glare in open areas.

Installation Notes

Existing mounting points were reused. No ceiling modification was required.

Spacing remained the same as the original HPS layout. We evaluated re-spacing during planning, but test illumination showed acceptable uniformity, so adjustments were not forced.

One immediate difference was startup behavior. The LED high bays reached full output instantly. That changed how early shifts started. No warm-up delay, no uneven brightness during the first minutes.

After Replacement

Measured light levels were higher than before, despite the lower wattage. Operators noticed it first near rack edges and loading paths.

Energy consumption dropped significantly. Based on site records, the warehouse estimated around 70% energy reduction, while perceived brightness increased by roughly 30% compared to the old system.

Maintenance planning changed. With a rated lifespan over 100,000 hours and a 5-year warranty, routine lamp replacement was no longer part of regular scheduling.

In a metal warehouse, removing that task matters more than it sounds.
