Secret Jardin Cosmorrow Power Supplie 40 Watt
The Secret Jardin Cosmorrow Power Supply 40 Watt (COM-40) is the official power supply for a single Cosmorrow 40W LED bulb. Growers purchasing standalone Cosmorrow bulbs rather than a complete TNOLED kit need this driver to connect the bulb to 230V mains supply. The driver converts mains voltage into constant current appropriate for optimal LED operation, protects against voltage surges, and extends bulb operational life. Compatible with all 40W Cosmorrow variants (Grow and Bloom spectrums). Important: one power supply per 40W bulb — to power two Cosmorrow bulbs, order two COM-40 units or choose the TNOLED 2×40W kit with integrated drivers instead.
Secret Jardin Cosmorrow Power Supply COM-40 — LED Driver for 40W Cosmorrow Bulbs
The Secret Jardin Cosmorrow Power Supply 40 Watt (COM-40) is the manufacturer-validated power source for Secret Jardin's Cosmorrow 40W LED bulbs. LED fixtures do not operate directly on 230V mains supply but require an LED driver that converts mains voltage into constant current at the correct voltage for the LED chips. This driver is specifically calibrated for Cosmorrow and forms part of the complete Secret Jardin TLED range for European growers assembling their own lighting systems from modular components.
Why a Dedicated LED Driver Is Essential
LED chips operate fundamentally differently than traditional incandescent or HID lamps. Where HPS or MH fixtures can be connected directly to mains (via a ballast), LEDs require constant current (CC) at a specific voltage profile. Without an appropriate driver, LEDs would burn out within seconds from voltage spikes, or flicker and perform poorly due to grid voltage variations. The COM-40 driver delivers stable current to the Cosmorrow 40W bulb and includes integrated protection functions against overvoltage, short circuits, and thermal overload. The outcome: the specified 50,000-hour operational life that Secret Jardin documents for its Cosmorrow bulbs, achievable only with validated drivers.
- Official Secret Jardin power supply: the only manufacturer-validated driver for Cosmorrow 40W bulbs.
- Compatible with all Cosmorrow 40W variants: operates with Grow (6500K) and Bloom spectrum bulbs alike.
- Integrated protections: overvoltage, short-circuit, and thermal safeguards for safe long-term operation.
- 230V AC compatibility: direct connection to European mains supply without additional equipment.
- One-to-one configuration: this COM-40 powers a single 40W bulb — for more bulbs, order additional units.
When Do I Need This Power Supply?
The COM-40 power supply is specifically intended for installations using standalone Cosmorrow bulbs. Growers choosing the Cosmorrow 40W Grow bulb as a separate component absolutely require this power supply to connect the bulb to mains. Conversely, growers opting for the TNOLED 2×40W Grow kit do not need to order this driver separately — the kit structure integrates the power supplies within the fixture housing. Separate purchase of bulb plus driver does offer more flexibility for building custom fixtures or replacing a single component in case of failure.
Bulb Selection: Grow or Bloom Cosmorrow?
The COM-40 operates identically with grow and bloom variants of the Cosmorrow 40W bulb, providing flexibility when configuring your setup. For growers supporting both vegetative and flowering phases with dedicated bulbs, the investment in two standalone Cosmorrow 40W (one grow, one bloom) plus two COM-40 drivers is a sensible choice. For bloom-focused setups, alternatives exist such as the TLED 42W Bloom at higher wattage — but this unit uses a different driver. The COM-40 is specifically dedicated to the 40W Cosmorrow platform only.

Why does a Cosmorrow bulb require a separate power supply?
LED bulbs do not operate directly on 230V mains voltage but require a driver that converts mains into constant current at the appropriate voltage for LED chips. Without an appropriate driver, LEDs would burn out from voltage spikes or flicker and malfunction due to grid variations. The COM-40 is specifically calibrated for Cosmorrow 40W bulbs and secures the stated 50,000-hour service life through stable current delivery.
Can I use this driver for a different LED bulb?
The COM-40 is specifically calibrated for Cosmorrow 40W bulbs — Grow and Bloom variants alike. Use with other LED bulbs is not advised because every LED has its own power profile. An incorrect driver can damage the bulb or pose a fire hazard. Always purchase the manufacturer-recommended power supply for your specific bulb — manufacturer warranties typically void when non-validated drivers are deployed in the installation.
How many drivers do I need for multiple Cosmorrow bulbs?
One COM-40 driver powers one 40W Cosmorrow bulb. For two bulbs, order two drivers. At three bulbs or more, it becomes financially attractive to switch to the TNOLED 2×40W kit combining two bulbs with integrated drivers in a single fixture. For larger installations, a combination of standalone Cosmorrow units and integrated kits often delivers the most flexible overall configuration.
Is the driver safe for continuous use in humid grow environments?
The COM-40 is engineered for extended use in typical cultivation environments, including elevated humidity up to approximately 70% RH. The housing provides protection against condensation and normal humidity fluctuations. For optimal longevity, position the driver outside the tent itself, in a dry location with adequate air circulation — this prevents overheating and extends the operational life of the internal electronic components.
