Recently one of our customers needed to replace multiple 400w metal halide high bay fixtures with LED high bay fixtures.

400w metal halide (MH) high bays were in a 100′ x 200′ shipping warehouse.

MH lighting was old and many of the fixtures didn’t work.

Our customer wanted to purchase LED lighting that would be more efficient than their previous fixtures.

Access Fixtures was able to step in, provide photometric data, and provide the customer with new LED

fixtures at a lower cost and higher efficiency than before.

Read on to find out how we did it!

Problems With 400w Metal Halides

The customer had numerous problems with his current 400w metal halide fixtures.

Frequent ballast failure was the biggest problem. Each time a ballast failure occurred, the customer would have to call an electrician to fix it.

With 25′ ceilings in the warehouse, this quickly became time-consuming and expensive.

Another major issue was the cost of running the fixtures.

MH lights used a lot of electricity, a whopping 460 system watts per luminaire. Even worse, MH lights suffer rapid lumen depreciation.

Over a short timeframe metal halide lights emit less light.

Risk of nonpassive failure was the last major problem that the customer was concerned about.

Nonpassive failure is a spontaneous explosion that can happen to metal halide lamps.

This rains hot glass on everything in the vicinity and the risk of this happening was too large for the customer to take.

A Better Solution for 400w Metal Halide LED Replacement

Non-efficiency of their current lighting was the main concern of the customer.

400w metal halide lamps emit about 36,000 initial and 24,000 mean (average) lumens.

As stated, our customer’s current 400-watt metal halide system uses about 460 system watts per luminaire, which uses a lot of power!

Access Fixtures lighting specialists determined that the lowest cost, most high-performance luminaire that would fit this customer’s application was an HIIO LED high bay.

Features of the Hiio

HIIO was specifically recommended with Selectable 200w/240w/300w.

Selectable Wattage:  HIIO Selectable 200w/240w/300w features selectable wattage.

Once installed, the customer, with the flick of a switch on the fixture, could set the fixture at 200 watts, 240 watts, or 300 watts.

Selectable 200w/240w/300w can emit 26,000 lumens, 31,200 lumens, or 39,000 lumens on the HIIO. No guesswork here.

The customer gets the amount of light that the customer wants.

Occupancy and Daylighting Sensor: An optional plug-and-play module HIIO Selectable 200w/240w/300w can be equipped with a programmable occupancy sensor and daylighting.

An occupancy sensor steps down the wattage when nobody seems to be in the area and shuts the light off after a while.

When someone returns to the area, the light is instantly on at the programmed light level desired. Wow!

The daylighting part of the plug-and-play module checks for the light level if the light is turned off.

If it has daylight savings in the area, the module will dim the light or shut it off saving even more energy.

Again if needed, the HIIO LED high bay light will return to the program/preferred light level.

More features and options:

IP65 Rating: Going back to basics, all HIIO LED high bay fixtures boast an IP65 rating which means it is suitable for dusty, damp, or wet locations.

An IP65 rating means the fixture is protected against multi-directional, low-pressure water jets.

In other words, customers can hose them off or blast off dust with an air compressor if needed.

Safer: HIIO, being LED, does not suffer from the risk of nonpassive failure, which means no raining shards of glass or fire to worry about!

Higher CRI: With a CRI of 70+, HIIO has better color rendering than a traditional metal halide fixture.

Endless On and Off Cycles: In contrast to traditional metal halide fixtures, the HIIO can handle endless on-and-off cycles.

Metal halides take time to heat up before they reach full brightness and their ballasts are damaged by turning them on and off too many times.

LED drivers are digital rather than combustion-based, they can handle being turned on and off without damage.

400w Metal Halide LED Replacement Efficiency Benefits

Energy use dropped by 50% 

  • It’s current 400-watt MH system used 460 system watts per luminaire
  • HIIO Selectable 200w/240w/300w set at 200 watts uses 200 watts 
  • HIIO Selectable 200w/240w/300w reduces wattage by 260 watts/luminaire 
  • Energy use will drop by about 57% before employing occupancy controls
  • Occupancy and daylighting controls will provide additional energy savings

To run this photometric, we used 16 HIIO 240s in 2 rows of 8 on the ceiling.

You can download the complete photometric analysis in the link to the right.

The result was a happier customer with more efficient lighting that will save them money in the long run.

Need A Photometric Analysis?

Interested in replacing old metal halide high bays with new LED models?

Looking for a 400w metal halide LED replacement?

Unsure how many to purchase and what fixture would be an appropriate one-to-one replacement?

We suggest ordering a photometric analysis.

A photometric analysis is a computerized simulation of the area that needs to be lit and run with fixtures that Access Fixtures manufactures and sells.

This simulation is then delivered as a report and can help you choose lighting for your next project.
