If you’ve looked at some of Mean Well’s larger HLG series constant voltage drivers, you may have noticed that some of the big boys have 2 sets of outputs leads (2 positive and 2 negative output wires), rather than 1. This can be a little confusing for newcomers, since the majority of the HLG series drivers only have a single set. Why would the big CV units have two?

In part 3, we examine A-type and B-type dimming for constant current drivers, including reviewing how each type works, what the pros and cons of each are, and how to dim multiple drivers simultaneously. Part 4 will cover A-type and B-type constant voltage drivers.
The Mean Well HLG line is the undisputed king of drivers in the DIY LED grow light world. The goal for this series of videos is to provide a complete breakdown of everything you need to know about them, whether you’re totally new to DIY LED, or a seasoned vet. We’ll be covering:
- Constant current vs. constant voltage and the pros and cons of each
- Series and parallel wiring, and when you might need to use each type
- A-type vs. B-type drivers and some considerations you’ll need to make when picking between them
- Dimming single and multiple drivers
- Reading the data sheets and applying the important specifications
- Matching any LED to a CC and CV driver
Part 1 of this series provides an overview on the different types of drivers within the HLG line and focuses on constant current models and series wiring.
