Lumens and candela are both lighting measurement units, but they measure different aspects of a lighting device. Knowing about the difference between lumens and candelas will help you choose lighting devices that are ideal for your workplace. More importantly, this knowledge will ensure that your lighting supplier does not cheat you. Some may try to convince you about the merits of a lighting device by quoting impressive lumens or candela numbers. However, they may not be relevant for your needs.
