Electronic ballasts made their debut in the hydro industry almost 10 years ago and they quickly stole the show. With their higher efficiency and adjustability, gardeners fell in love with everything except the price. DL Wholesale ALWAYS keeps it on the DL and that includes price. Our newest collection of digital ballasts are called B-Lite and are offered in 600w, 1000w, 120v, 240v, and 277v.
