600W Metal Halide Replacement with LED High Bay: XJ-HBL150W Project in Germany

Project Location: Germany
Application: Industrial Workshop
Original Lighting: 600W Metal Halide
Replacement Model: XJ-HBL150W-2
Brand: SEEKINGLED

This record was written after the new lighting had been installed and operating under normal workshop conditions.

The project started with photos. The customer sent images of the existing workspace, and the situation was clear immediately. The workshop was running under 600W metal halide lamps that had been in service for many years. Light output had dropped heavily. Some fixtures were still on, but the space between them felt uneven and dim.

People were working there every day. That was the part that mattered most at the beginning.

Initial Evaluation

The first step was not product selection, but understanding how bad the situation actually was. Based on the photos and basic layout information, it was obvious that a direct one-to-one replacement would need careful checking.

For safety, we started the Dialux calculation using XJ-HBS200W high bays. This is a common assumption when replacing 600W MH lamps. The results showed that the lux levels would exceed what the workshop actually required. Too much light brings its own problems.

So we paused there.

Recalculation and Adjustment

The next step was testing the XJ-HBL150W LED High Bay Light in the same layout. Lower wattage, different optical behavior. The recalculated results landed closer to the target range. Not minimal, but reasonable for the type of work being done.

At that point, the decision was less about saving energy and more about not over-lighting the space.

Installation and On-site Outcome

After installation, the difference was immediate. The workspace no longer relied on isolated bright spots. The floor, workbenches, and vertical surfaces were readable again. Shadows were still present, but no longer dominant.

From an energy standpoint, the reduction was clear. Compared to the old 600W MH system, overall consumption dropped by up to 75%. That was documented, but it was not the primary concern during handover.

The more important part was that the workshop no longer felt neglected. Lighting became functional again.

No follow-up requests were made after commissioning.

This 600W Metal Halide Replacement with LED High Bay project was not complex in structure. It was driven by real working conditions and corrected step by step until the balance felt right.
