Lighting in your workplace is critically important to your staff’s ability to accomplish tasks efficiently and safely. In addition, proper light levels prevent eye strain, which allow us to work comfortably for longer periods of time.
Light is measured using lumens and lux. Lumens are used to measure the amount of light being given out by a bulb. For example, a High Bay 200 watt LED light gives off 25,000 lumens.
Lux measures the amount of light reaching a surface. One Lux is equal to one Lumen per square meter.
While some lights may have a high lumen output when first installed, the level of lighting can depreciate quickly, this is another reason why LED lights provide a good replacement option.
The table below highlights the lux levels required to ensure efficient operation of your workplace.
|Computer workstations||300 – 500|
|Large item processing or assembly||300|
|Small item processing or assembly||500 – 1000|
|Inspection and testing||500 – 2000|
|Packing & Dispatch||300|
If you are concerned that your lighting is not at the required level EAS can conduct lux measurements to assess your current level of lighting and where improvements may be required.
This can also provide a good opportunity to consider upgrading to LED lights which also offer the benefits of:
- Increased lifespan
LED lights have a lifespan of 50,000 hours and include a 5 year warranty compared to Metal Halide’s which carry no warranty and have a lifespan of just 5 years. Most Metal Halide light fittings in use today will be past their 5-year lifespan and their lumen output would be well below their maximum output of 32,000 lumens; while still using full power input of 400 watts. The lumen output of a metal halide lamp depreciates much faster than an LED. In fact, they depreciate about 20% each 1,000 hours.
- Reduced Power Consumption
High bay LED lights have a lumens/watt ratio of 125 vs Metal Halide Light with 80 lumens/watt.
This means the LED light is 56% more efficient than its Metal Halide counterpart and this efficiency only improves over the lifetime of the fitting as the lumens in a metal halide light depreciate quite rapidly while the LED lumen output hold steady.
- Better Lighting
LED lights emit light over 180° vs the standard metal halide light which emits light in a 360° range. With the LED light, lighting is being directed where you need it, so your energy consumption is reduced – saving you more money.
- Reduced Maintenance
With a lifespan of 50,000 hours the LED lamp will require less changes which means less maintenance work for your team and less interruption to your business.
With LEDs there is also less chance of glass breakage over essential product areas such as bulk stores and process areas in your plant.
