The Secret Jardin Cosmorrow 40W Growing LED bar is a thoughtfully designed lighting tool created to excel during the vegetative phase of plant development. Operating at 24 V and drawing just 40 W, this sleek 90 cm bar projects a cool 6500 K light that encourages robust vegetative growth, making it especially well-suited for seedlings, cuttings, and mother plants under propagation. It delivers around 4,800 lumens with a photon flux of approximately 88 µmol/s, resulting in reliable energy efficiency in the range of 2.0 to 2.7 µmol per joule, depending on the testing source. Built to endure demanding indoor environments, the Cosmorrow Growing bar is IP65-rated for water and dust resistance and constructed with a durable, passive thermal design that produces minimal heat. The Secret Jardin Bulb HPS250W grow lights are highly effective, but if you want to dip your toes into other devices, then check out their HPLED 200W Full Spectrum or even the Bulb HP400W.
