Know the contents before buying
5 bars rated at 20 W, the power supply and frame of the Cosmorrow 100 W kit. A suitable timer if needed, and growing equipment other than lighting.
Getting started
Install, connect, then observe
01
Mount with power disconnected
Unplug the power supply and use fittings suited to the support. Keep the light and cables secure.
02
Connect each bar to its output
Work with power disconnected, use the intended outputs and stay within the supply rating. Adding bars does not turn a 200 W supply into a 280 or 360 W supply.
03
Adjust to the crop
Follow your version’s instructions, observe plants and measure temperature. A distance used in a test is not a universal rule.
Looking after your equipment
Unplug the entire system before working on it. Allow to cool, dust the bars and check connectors and hangers. Do not remove Cosmorrow’s transparent sleeve. Use only confirmed compatible replacement parts.

Frequently asked questions
Your questions
What is the electrical consumption in kWh of the Cosmorrow 100W kit during a typical 8-week flowering period?
Nominal power is 100 W: energy = 0.1 kW × operating hours. Over eight weeks, multiply this power by your selected daily hours and 56 days.Cost depends on your tariff. Measure supply losses and other devices at the outlet; these calculations do not prescribe a photoperiod.
Is the 100W power of the Cosmorrow kit sufficient to maintain optimal blooming over an area of 60x60 cm, especially for light-demanding orchids like Phalaenopsis?
Wattage and length alone do not guarantee coverage, plant count or penetration through dense foliage. Check dimensions, then light at the centre and edges for the plant stage. Different species may need different levels or schedules.
What is the real luminous output of the Cosmorrow 100W kit compared to other HPS or LED solutions for a surface of 60x60 cm? What is the precise electrical consumption and real cost with the current EDF rate?
The precise figure requested is not confirmed for the revision and measurement conditions in your question. PPF is total emitted photon flux; PPFD is the light received per square metre at a specified distance and grid. No validated map for the height and setup in your question is provided here. Lumens do not convert directly to PAR, and these measurements do not predict grams per watt.
This light guarantees no yield quantity, growth speed or disease prevention. Species, received light, climate, water and nutrition work together. Comparing HPS, CMH or another LED requires matched test conditions.
Wattage and length alone do not guarantee coverage, plant count or penetration through dense foliage. Check dimensions, then light at the centre and edges for the plant stage. Different species may need different levels or schedules.
Nominal power is 100 W: energy = 0.1 kW × operating hours. Without a fixed daily duration, one daily or monthly total would not be justified. Cost depends on your tariff. Measure supply losses and other devices at the outlet; these calculations do not prescribe a photoperiod.
Possible integration with voice assistant for remote light control? Completely waterproof system compatible with installation in humid environments? Can we automate the transition between growth and bloom phases with this 100W kit?
No connected control or built-in dimming is documented for this version. A compatible timer or switched outlet can control mains power to the supply; this does not add dimming, spectrum adjustment or temperature/humidity sensing. Check load and inrush-current ratings.
No single distance suits every plant and layout. Follow the instructions for the version supplied, allow for mountings and adjust using light and temperature measurements. Side lighting supplements a specific area; it does not guarantee the same distribution as overhead mounting.
The IP65 rating of Cosmorrow bars concerns dust and water-jet protection; it does not permit immersion or make every supply and connection waterproof. Keep connections dry and retain the protective sleeve. Hydroponic use does not remove these precautions.
Install with power disconnected, using the intended fittings and checking support strength. Allow room for cables and moving neighbouring equipment. Straightforward assembly still requires following the exact model’s instructions.
How to optimize the management of growth and flowering with the Secret Jardin Cosmorrow 100W kit while considering its modular and waterproof lighting for a 60x60 cm space?
Blooming / Full Spectrum combines several visible components for growth and flowering. It does not automatically change with plant stage. Kelvin describes light colour and nanometres describe wavelength: these are different quantities.
The IP65 rating of Cosmorrow bars concerns dust and water-jet protection; it does not permit immersion or make every supply and connection waterproof. Keep connections dry and retain the protective sleeve. Hydroponic use does not remove these precautions.

This light guarantees no yield quantity, growth speed or disease prevention. Species, received light, climate, water and nutrition work together. Comparing HPS, CMH or another LED requires matched test conditions.
If a fault occurs, contact GrowLED with proof of purchase, model and a description of the fault. Support depends on diagnosis and applicable terms; no replacement time or undocumented electrical protection is promised.
To replace a bar, identify the exact model, generation, length, voltage and wattage. Older 90 cm and newer 70 cm bars cannot be swapped without checking the frame. Price depends on the available part; check its current listing or ask GrowLED.
Is the Cosmorrow 100W kit optimal for SCROG cultivation in a 60x60 cm space with LED, and can we adjust the intensity to improve flowering under LST?
Wattage and length alone do not guarantee coverage, plant count or penetration through dense foliage. Check dimensions, then light at the centre and edges for the plant stage. Different species may need different levels or schedules.
What is the precise light spectrum of the Cosmorrow 100W kit for flowering and how is it suitable for different stages of plant growth in hydroponics?
Blooming / Full Spectrum combines several visible components for growth and flowering. It does not automatically change with plant stage. Kelvin describes light colour and nanometres describe wavelength: these are different quantities.
The IP65 rating of Cosmorrow bars concerns dust and water-jet protection; it does not permit immersion or make every supply and connection waterproof. Keep connections dry and retain the protective sleeve. Hydroponic use does not remove these precautions.
What is the operating temperature of the Cosmorrow 100W kit and does it require a specific cooling system to avoid overheating in a 60x60 cm space?
This LED produces heat: low wattage or passive cooling does not mean no heating. Keep components ventilated and measure temperature near foliage. No fixed surface temperature or quantified comparison with another light is verified for all conditions.
Wattage and length alone do not guarantee coverage, plant count or penetration through dense foliage. Check dimensions, then light at the centre and edges for the plant stage. Different species may need different levels or schedules.
Is the Cosmorrow 100W kit really effective for SCROG cultivation of 60x60 cm under LED, particularly in terms of uniformity and light penetration during flowering?
Wattage and length alone do not guarantee coverage, plant count or penetration through dense foliage. Check dimensions, then light at the centre and edges for the plant stage. Different species may need different levels or schedules.
Is integration possible with a voice assistant to manage the time slots of the Cosmorrow 100W kit?
