Before you choose
Check mounting and power supply
Allow for the 87 cm physical length plus fittings and cables. Usable coverage depends on height, lamp arrangement and plant light requirements. Check the layout before choosing.
The 50 and 90 cm formats have physical bar lengths of 47 and 87 cm. Bar length is not illuminated coverage. Use alongside the main light, never as the sole source.
What is included
One Cosmorrow LED bar.
What you need to add
Compatible 24 V DC power supply sold separately. Choose an output rated for each 40 W bar, compatible mountings and a timer if needed.

Practical choices for your setup
Choose according to available space, plant stage and existing equipment.
730 nm + 2100 K white
The supplement changes the spectrum reaching plants. Its effect depends on species, main lighting and exposure; it does not replace the main light.
Separate components
Choose the Cosmorrow bar and power supply separately. A compatible part can be replaced without replacing everything; check the generation and connectors.
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 compatible parts
Check voltage, rated capacity and connectors before powering on. Never connect a 24 V bar directly to mains.
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 and allow to cool before cleaning. Gently remove dust and check fittings and cables. Do not remove a Cosmorrow bar’s transparent sleeve: it is part of its protection.

Frequently asked questions
Your questions
Can this infrared LED bar really boost plant growth without heating the air around or increasing my electricity bill?
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.
Nominal power is 40 W: energy = 0.04 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.
Is the Cosmorrow Infrared LED bar 40W 90cm compatible with lighting automation systems to adjust intensity according to the growth stage?
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.
What is the compatibility of the Cosmorrow Infrared 40W LED bar with other types of horticultural lamps in the same installation to optimize growth without interfering with thermal regulation and light uniformity?
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.
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.
Can the Cosmorrow Infrared LED Bar 40W 90cm be effectively combined with a main LED lighting to optimize SCROG or LST techniques without overheating the plants or affecting the yield?
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.
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.
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.
Is the heat level generated by this 40W LED bar really lower than that of an equivalent CMH lamp to avoid thermal stress in growing plants?
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.

Is the Cosmorrow Infrared 40W 90cm LED bar effective for stimulating the flowering phase in hydroponics without increasing the ambient temperature?
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.
