Product questions
Your questions about this product
- Is the 1x40W transformer compatible only with Cosmorrow LED bars or can I use it with other similar LED bar models?The 1x40W transformer for Cosmorrow LED bars is specifically designed for these bars. Its use with other similar LED bar models is not guaranteed nor recommended, because the voltages, powers, and connectors must perfectly match to ensure safe and optimal operation.
- What is the electrical efficiency in W to output for each model (1x40W and 2x40W) of this Cosmorrow power supply? Optimizing the efficiency would help me better calculate the consumption and thermal management of the system.
Regarding the Cosmorrow 40W power supply (1x40W or 2x40W) from Secret Jardin, there is no official information available about the precise electrical efficiency (W consumed vs. W delivered) in our database.
Generally, modern LED horticultural power supplies have an efficiency often around 85 to 90% depending on quality and load, which allows estimating consumption and thermal management. For example, for a 40W model, one could expect an input consumption of about 44-47W, and for 2x40W, around 88-94W in total.
For optimal management, consider measuring the actual consumption if possible or use an estimated efficiency in your calculations. This also helps anticipate generated heat.
- Cosmorrow 40W Power Supply Secret JardinA transformer that stands the test of time is no small feat. Which one between the 1x40W and the 2x40W offers the best long-term stability?And what about thermal management?
