Lighting products are full of specifications. Some of them impact the overall performance of the lighting system, and some of them make a significant impact on light levels, color, or energy consumption.
When it comes to ballasts, do you know what to look for? Ballast factor is one of those often overlooked or misunderstood specs that can make a big difference in your linear fluorescent lighting system.
In this article, we’re answering three key questions related to ballast factor. You can click on the questions to jump ahead to the section.
If you're new to commercial lighting, the concept of a ballast can be an odd one. You’re probably used to just screwing light bulbs into sockets and flipping switches. The transition to ballast-dependent lighting technology can be frustrating and confusing.
Have you ever heard a light bulb buzz?
Technically, no. The buzzing you hear is coming from the ballast, not the bulb itself.
Nerdy lighting technicalities, I know. Ballasts, light bulbs – it's all the same, isn't it?

If you still have T12s in your building and they run on magnetic ballasts, you may soon face a problem: what do you do when your ballasts die?
Unlike fluorescents, some linear LEDs do not need a ballast to power up and produce light. So, a lot of our customers have been asking us about the safety of just bypassing the ballast and direct-wiring their LED tubes.
Although LED lighting is the most popular and one of the most efficient lighting options right now, our team still faces a lot of questions on fluorescent lighting. Aletheia Cyr, our training and development specialist, helps walk through some of the most common questions we receive on fluorescent lighting.
We’ve written separately on the blog about energy savings calculations and ballast factors with ballast-dependent lighting, but how do these two topics come together? This can be a really tricky topic in lighting if you’re new to ballast factors.
