250W Electronic encapsulated electronic ballast, perfect for the lighting system in indoor marijuana growing due to its efficiency and light weight.
This ballast incorporates a microprocessor that ensures a constant electric current and provides the maximum amount of lumens at all times. This will help plants achieve their full potential (relative to the 250W they receive) and will extend the life of the bulb by making it suffer less stress.
Furthermore, it boots really fast and achieves maximum power after about 1 minute compared to the 20 minutes needed by traditional ballasts. It is also much lighter than traditional ballasts at only 4kg.
Includes electronic protection and thermal protection, and it is really quiet.
Includes two fastening brackets.
Adjusting the electronic ballast with dimmer switch (4 positions):
50%, 75%, 100% et Super Lumen.
