If you’re shaking your head at the moment, I don’t blame you. The above statement is logic which escapes consumers and LED manufacturers alike- including Empyrean Lighting once!

An overriding philosophy in the development of new LED luminaires and lamps has been to design products that either 1) look exactly like it’s traditional counterpart (luminaires) or 2) works/fits in a traditional fitting for ease of retrofit (lamps).

The merits and inherent problems of point #2 will be the topic of a future post, but here I would like to address point #1, and specifically in relation to high and low bay lighting.250W-400W-Metal-Halide-High-Pressure-Sodium-Industrial-High-Bay-Light

Let’s firstly consider a traditional high bay light used typically in industrial warehouses for close to the last century. They are usually ~400W metal halide, mercury vapour or high pressure sodium lamps which fit into the large conical fittings where the lamp is recessed into the bell shroud which extends ~.5m below the ballast, starter, and other control gear.

These lamps are relatively inefficient, use large start-up currents, contains significant amounts of mercury, are difficult to dim or control, have multiple failure points, do not start-up immediately (re-strike time) and have maximum lifespans around 20,000 hours.These facts have made replacement of this technology a prime target for consumers and LED luminaire manufacturers alike.

Untitled_226The problem is that both groups are trending toward designs which mimic the traditional design and appearance the high bay light. Whether the lack of vision is due to trying to promote consumer confidence by minimizing change, or a lack of creativity by designers, one can’t be sure. But what is apparent is that substituting these radically different light sources within the same design does play to the strengths of the LED, and worse will leave consumers disappointed.


Consider the following reasons to choose a purpose designed LED highbay (such as our Andromeda Series) over the alternative –

Thermal Management
Single Point Failure
Restricted driver (ballast/transformer) Access
Beam Angle & Variance
Strength of fitting
Light Projection Surface

Andromeda Flood Luminaire

In a recent project, another supplier had recommended bell shaped LED highbays at 250W and 100lm/W – the Andromeda’s we specified (after simulating to required lux levels) were 200W and 110 lm/W. Significant power savings when weighted up over ~222 luminaires.

in the project. Further, due to the tighter beam angles of the LED bell-shaped luminaires 10% more luminaires would have been required to meet the lux levels provided by our solution. Choosing a better, purpose built Andromeda series luminaire will save you money – both short term and long term.

So if you’ve made the tough decision to switch over to LED technology for your facility, please make the easy decision to choose purpose built LED technology to ensure your project is a success.
