Review on π‘ Hydrofarm Quantum QT400 Dimmable Ballast for 400W Grow Lights by Michael Cormier
Might not be worth the trouble.
Have been using Quantum ballasts for five years. Quantum 2 is quieter. But the last FOUR Quantum 2 ballasts that Revain sent me don't work. Every possible combination has been tried many times in a fully functional system. I was hoping to replace my backup Quantum One, but it still replaces another dead Quantum Two. Four non-functioning quanta in a row. How does this happen?!
- Easy to use
- There are some nuances
