The Agrolite Darknight 20W Green LED bulb allows you to work in indoor grow rooms and tents during the dark period without disrupting the physiological rhythms of cannabis plants . It emits 510nm green light, has a 20W rating, and uses an E27 socket, making it ideal for quick maintenance with minimal energy consumption.

The Agrolite Darknight 20W Green LED Bulb is designed for inspection, irrigation, minor pruning, or weather checks during nighttime. Its wavelength of approximately 510 nm is comfortable for the human eye but generates a very low photosynthetic response, so the canopy remains in "night mode" while essential tasks are performed.
The E27 format facilitates immediate mounting in standard lamp holders, and the 20W consumption allows for an efficient work point in corridors or closet corners without raising heat or humidity.
Compared to makeshift solutions, this lamp concentrates the spectrum into functional green to avoid red/blue stimuli, which govern growth and flowering. The result: less stress, less hermaphroditism due to light pollution, and stable cycles in cannabis cultivation .
In daily practice, it is advisable to direct the beam towards the service corridor, use it only for the necessary time, and combine it with silent extraction so as not to disturb the microclimate.
In mixed installations with LED grow lights , the Darknight acts as an auxiliary tool that does not interfere with driver or controller programming.
Built to withstand frequent power-ups, it is a simple, economical and very practical resource for professional and amateur teams seeking precision in nighttime routines.
In indoor growing, the priority at night is protecting the photoperiod. This bulb creates a working environment where you can walk around, observe, and manipulate the plants without triggering daytime signals. It allows you to check automatic irrigation systems, detect leaks, observe passive pests, and measure parameters without disrupting the plants' dormancy.
It provides working light during the dark phase of cannabis plants and other photosensitive crops. It facilitates tasks such as adjusting ventilation, checking EC/PH, repositioning supports, or inspecting netting, minimizing the risk of interrupting flowering photoperiods and preventing yield reductions due to light pollution.
A cost-effective solution for protecting blooms. A low-cost investment that prevents losses due to light stress and ensures professional maintenance during critical times.
