Spider Farmer® GlowR40 Deep Red Spectrum 660nm Supplementary LED Grow Light

The SF-GlowR40 LED grow light (650-665nm) promotes photosynthesis during the flowering and fruiting phases and ensures strong plant growth.

Power – 40W (20W per light bar; 2 pieces)
Light size: 62.8 cm 4.6 cm 3.7 cm (1 piece)
Maximum daisy chain number: 16 individual strips (110V) / 32 individual strips (220V)

The GlowR40 is ideal for use under 500W (for reference: SF2000 / SF4000 / G4500 / SE4500 / SE5000 / G5000). It can also be hung separately horizontally or vertically in any grow room. The design fits most lamps for added safety and ease of use.

Red LED diodes (650-665nm):
Utilizing the red light spectrum at 650-665nm is crucial for the growth phases of plants. This specific wavelength of red light plays an important role during the flowering and fruiting phases and improves yield.

IP65 Waterproof Transparent Lamp Cover:
The SF-GlowR40 is equipped with an IP65 waterproof transparent lamp cover, which effectively protects the LEDs and circuits from moisture. This feature ensures normal operation even in high humidity environments and extends the service life of the product.

Daisy-chain design:
Designed with daisy chain functionality, the SF-GlowR40 can connect up to 16 light strips in series at 110V or up to 32 light strips in series at 220V. The SF-GlowR80 can connect up to 8 light strips in series at 110V or up to 16 light strips in series at 220V.

Multiple installation methods:
Supports various installation methods including bottom, side, bottom and top lighting of tents or rooms. This flexibility solves potential problems in plant growth, such as uneven light distribution due to different plant heights, leading to improved cultivation results.

Digital Programmable Timer:
Equipped with a digital programmable timer that allows users to create lighting schedules based on plants' growth stages and specific requirements. This smart design helps maximize plant productivity.
