You already have Vanguard magnetic ballast with 315W LEC technology at PEV Grow, one of the most recommended in the market for its high quality/price ratio.
This ballast is only compatible with Lec 315w bulbs, as it has a thermal protection system that all Lec 315w bulbs require, which is the main reason why they cannot be used with other brands of lamps.
It should be noted that this Lec magnetic ballast works with a series of numerically controlled pulse ignition sequences, extending the life of the bulb. In less than half an hour after the lamp is switched on, it is ready to work at full capacity.
