Bolt EDB Electronic Ballast 400W – Dimmable Plug and Play Ballast for HPS and MH

Bolt EDB 400 W electronic ballast for HPS and MH lamps at 220-230 V. Closed housing and plug and play installation: plug it in and connect the reflector, with no wiring needed.

Dimmable, and that matters

Unlike electromagnetic ones, this ballast does allow power adjustment. This makes it possible to start gently in the first weeks of growth and increase to full power during flowering, using the same lamp and the same setup. Being electronic, it also weighs much less (2.5 kg versus 4-5 kg for an electromagnetic one) and has lower losses.

⚠️ Clearance product

The supplier has marked it as clearance: the price is promotional, not the regular list price, and the stock is limited. Once it runs out, there will be no restock at this price.
