Sanlight Flex II 4-Way Splitter 19/19

The Sanlight Flex II 4-Way Splitter lets you branch a single Flex II data and power feed into three panel connections plus a dedicated downward extension port. It is the correct choice for growers building multi-tier Flex II installations who need orderly, manufacturer-matched cabling.

The splitter uses the 19-pin connector format native to the Flex II series. One input feeds four outputs cleanly. Three of those outputs accept Flex II 10 or Flex II 20 panels directly. The fourth output is reserved for the dedicated Sanlight extension cable that drops to a lower growing tier.

Multi-tier growing demands precise light distribution at every level. Using this splitter, you can position three panels across one shelf while simultaneously feeding the tier beneath. There is no need to run a separate power cable back to a driver or control unit for the lower level. The signal and power travel through the splitter cleanly.

This accessory is not compatible with Flex II panels and cables that use a different pin count. Confirm you are working entirely within the 19/19 Flex II ecosystem before purchasing. Mixing connector standards will not work and could damage equipment. If you are unsure, check the cable label on your existing Flex II components.

Pair this splitter with Sanlight Flex II extension cables and additional Flex II 10 or Flex II 20 panels to build out your installation methodically. Plan your tier heights and cable runs before mounting panels, as the splitter position determines how far the extension cable needs to reach to the shelf below.

Grower’s Note: In multi-tier setups, light intensity drops sharply between levels if the lower tier relies solely on spillover from above. Using this splitter to feed dedicated panels to the floor tier ensures each canopy gets direct, measured light rather than secondhand diffuse light. Measure the PPFD at each tier separately after installation and adjust panel height accordingly.
