Sanlight Flex II 4-Way Y-Splitter (WDC21 Male / 4× WDC19 Female)

The Sanlight Flex II 4-Way Y-Splitter lets you run four Flex II light panels from a single driver output without additional wiring work. It suits growers who want a tidy, scalable installation across a 150 W, 240 W, or 320 W Flex II driver.

The splitter carries one WDC21 male plug on the driver end. From there, four WDC19 female sockets branch out to individual Flex II panels. The 105 cm trunk cable reaches from a ceiling-mounted driver down to canopy level without straining connectors or creating tight bends.

Each branch lead runs 15-30 cm. That short drop is enough to connect a panel hanging directly beside the trunk. Position your fixtures symmetrically and the branch lengths keep cables neat rather than looped across the ceiling.

Use this splitter when you are building a multi-panel array under a single Flex II driver. A 320 W driver paired with four Flex II panels covers a larger footprint than two panels on a straight cable. The splitter makes that layout straightforward and avoids daisy-chaining, which can introduce voltage drop on long runs.

Pair this splitter with Sanlight's Flex II mounting rail or suspension wire kit so all four panels sit at the same height. Equal spacing and equal cable lengths mean even light distribution across the canopy, which matters during the stretch phase of flowering.

Grower’s Note: When splitting power across four fixtures, confirm your total panel wattage does not exceed the driver's rated output. The Flex II 240 W driver, for example, should not be loaded beyond its capacity even if four connector slots are available. Check each panel's individual wattage and sum them before finalising your configuration.
