Tips for Improving Lab Lighting
Lighting is fundamental in a laboratory’s work environment as it directly affects the performance of those who work in the lab. For instance, a large number of lab personnel are required to complete intricate tasks that allow for no margin of error. To improve productivity, personnel are encouraged to implement the below suggestions:
1. Replace light bulbs on a regular basis
The accepted average lifespan for the relevant light bulbs is:
| Light Source Type | Average Life Hours |
| Incandescents | 750 – 2,000 |
| Halogens | 2,000 – 4,000 |
| Compact Fluorescents (CFLs) | 8,000 – 12,000 |
| Fluorescents | 10,000 – 60,000 |
| HID (Metal Halide, HPS, and LPS) | 10,000 – 24,000 |
| LEDS | 25,000 – 50,000 |
2. Frequently clean light fixtures
Open topped light bulbs are recommended in the lab environment as they accumulate less dust when compared to closed top light bulbs. To clean your light fixtures effectively, use either a feather duster or a lint-free cloth (do not use water to avoid an electrical shock).
NEVER use cleaning sprays or agents to clean light fixtures as it can cause a fire or a short circuit.
3. Location, location, location
Position all the workstations in the lab, where possible, with the light source either above or in front of the worker. If the light is placed behind the workstation, the light source will cause a glare on the monitor. It is suggested to take in account the positioning of windows for natural light. To provide focused lighting for detailed experiments or measurements, a desk lamp can be ideal for additional lighting.
4. Colour balance
> Incandescents: The warm, yellow-amber light will produce more vivid reds, oranges, and yellows while muting blues and greens.
> Fluorescents: This flat and cool light enriches the blues and greens.
> Halogens: These white lights resemble natural light and make all colours look more vivid. Using halogens would make the shift from daylight to artificial light less jarring.
> Compact Fluorescents (CFLs): Produce either a warm white, neutral, or bluish-white light.
> Light-emitting diodes (LEDs): LEDs are becoming more popular as they can be dimmed and provide colour control. Furthermore, they do not emit infrared or ultraviolet.

In conclusion, if these tips are implemented in the laboratory it is guaranteed that the productivity and the personal health of employees will improve
