Maxibright Quad Timer 4 x 600W Grow Light Controller

Switch Four Lights From One Heavy-Duty Timer

The Maxibright Quad Timer is a heavy-duty grow light timer built to run 4 x 600 watt or 2 x 1000 watt lights from a single unit, and it needs no separate contactor or relay. That is four times the load of a typical heavy-duty timer, most of which top out at 1 x 600 watt. It is certified under British safety standards, handles a 13-amp load, and sets on and off times in 15-minute segments so photoperiods land exactly where you want them.

Key Benefits

• 4 x 600W or 2 x 1000W capacity from one timer, covering most small and mid-sized rooms
• No separate contactor or relay required, which saves both cost and wall space
• 13-amp load rating with switching built for the inrush current of ballasts
• 15-minute segments for precise control of your plants’ photoperiods
• Certified under British safety standards for peace of mind on a long-running circuit
• Consistent light cycles, keeping flowering on track

Timers That Cannot Cope With a Full Light Load

Domestic plug-in timers are the most common weak point in a grow room. Push more than one lamp through one and the contacts pit, stick or fail outright, and a light cycle that drifts or misses a day is enough to trigger excessive stretch, uneven flowering and low yields. Running all four lamps through a single correctly rated switch keeps the photoperiod identical every day and removes the tangle of daisy-chained timers behind the ballast shelf.

How to Use

• Check your total load stays within 4 x 600W, 2 x 1000W and the 13-amp rating
• Plug ballasts into the timer outlets, not into secondary timers or adaptors
• Set on and off times in 15-minute segments, typically 18/6 in veg and 12/12 in flower
• Mount off the floor, away from spray and standing water
