The Interlighting system by Philips is a supplemental lighting solution designed to deliver light within the plant canopy, not just from above. Perfect for tall, densely-leafed cannabis cultivars, it emits targeted photosynthetically active radiation (PAR) horizontally — stimulating lower bud sites and improving overall plant development. This makes it especially effective in high-wire or vertical grow systems. Equipped with energy-efficient LED technology, it produces minimal heat, allowing it to be placed close to plants without causing stress — perfect for optimal light distribution in tight indoor setups or greenhouse environments, promoting more uniform growth, higher yields, and better flower consistency from top to bottom. For growers that want to pair side lighting with robust overhead output, the Philips Toplighting Linear provides broad-spectrum, high-efficiency performance from above. If you’re aiming to support propagation or compact veg stages with precision, the Philips Production Module 3 offers focused LED power in a low-profile design.
