Tmasmanswered grow question 3y ago Dude, first of all, you're missing some parts.
You need
1 lamp
2 ballast
3 ignitor
4 optional starter
Let me see if I can help you out
Power supply, brown or black wire and blue wire.
Brown connects to the ballast, input (1) and goes out (3) from 3 to connect to the ignitor (R), from the ignitor it goes out (L) to the brown of the lamp. Brown is set.
Blue goes into the ignitor (N) and comes out the same (N) to the blue of the lamp.
Attention to lamp wattage W, the equipment must be equivalent in wattage.
For example, a 600w lamp with 400w equipment won't work.
