About Lighting Controllers and Accessories
Timers and contactors
A single LED or a 600W lamp on a standard socket can run from a plug-in timer such as the Optimum or the Time-R. Anything more needs a contactor: the timer sends a small signal and the contactor's relay switches the heavy load, so the timer never burns out. Maxiswitch 2-way, 4-way and 6-way contactors and the Loadstar 8-way run several lamps from one timer; the 12+2 and 16+2 contactor boards run a whole room.
LED controllers
The Maxibright Daylight controller runs Daylight PRO fixtures together: one schedule, sunrise and sunset dimming, and a temperature sensor that dims the lights if the room runs hot. The Varidrive controller does the same for Varidrive fixtures, and the Dimlux Maxi controller for Dimlux. Link cables daisy-chain the fixtures.
Accessories
Easy-Rolls hang a light and let you adjust the height with a pull. The Maxibright PAR meter measures the light actually reaching the canopy, which is the number that matters. PAR and PPFD are explained in LED grow light wattage by tent size.
Growers' Guides
- LED Grow Light Wattage by Tent Size (and LED vs HPS)How many watts of LED a tent needs: 300-500 W/m² in flower, a table by tent size, the Maxibright, Gorilla and Adjusta-Watt fixtures that fit, and LED vs HPS.
- LED or HPS? Why the Best Growers Use BothTom's view from twenty years in the shop: run LED as the main light and add a dimmable HPS, metal halide or CMH for flowering weeks 3-7 for a better finish.
