There are many suppliers of tunnel lighting products today. Although the quantity of the products has drastically increased in the past decade, sadly the quality has gone down.

Apart from the quality problems from dubious producers, the market is flooded with counterfeit products trying to fool the buyers with the good names honest companies have build over many decades.

Therefore it is very important that tunnel project procurement departments work with tunnel lighting consultants and that they start doing so in the very early stages of the project.

To help potential buyers, I would like to maintain a list of reputable companies. I hope it will help. By the way, I do not have any association with these companies unless I specifically mention so in line with my policy of full transparency.

• Philips - Global lighting company with consistent quality.
• TRT Lighting - A UK-based reputable tunnel lighting company.
