Spider Farmer G4500 320W Full Spectrum LED Grow Light

The Spider Farmer G4500 320W Full Spectrum LED Grow Light is a high-efficiency bar-style fixture designed specifically for rectangular grow spaces, delivering uniform light distribution, smart wireless control, and excellent value for growers using 2' × 4' or 3' × 5' grow tents.

Drawing only 320 watts while producing 913 µmol/s PPF at an efficiency of 2.85 µmol/J, the G4500 delivers strong full-spectrum performance with low operating costs. Its elongated bar-style layout is designed to evenly illuminate rectangular canopies where traditional square fixtures often leave darker edges and corners.

Built around Spider Farmer's latest G Series platform, the G4500 utilizes premium Bridgelux LEDs arranged at high density across multiple aluminum light bars. Spreading power across more diodes allows each LED to operate more efficiently while producing less heat, resulting in improved reliability and consistent canopy penetration.

Integrated Bluetooth and WiFi connectivity provide complete wireless control through the Spider Farmer mobile app. Growers can remotely adjust brightness, create custom lighting schedules, automate sunrise and sunset simulations, and manage multiple fixtures from virtually anywhere.

The elongated fixture is optimized for 2' × 4' flowering spaces while providing maximum coverage extending to 3' × 5'. Its open aluminum bar design improves passive cooling by allowing air to circulate freely between each light bar, while the removable external driver can be mounted outside the grow tent to further reduce internal temperatures.

The balanced full spectrum supports every stage of plant development from seedling through harvest and is suitable for soil, coco, hydroponic, aeroponic, and aquaponic growing systems.

Designed for growers who want professional performance without premium pricing, the G4500 combines uniform rectangular coverage, smart controls, efficient Bridgelux technology, and Spider Farmer's 5-year manufacturer's warranty into one versatile lighting solution.

High-Density Bridgelux LEDs

The G4500 utilizes premium Bridgelux LEDs arranged at high density to maximize efficiency while minimizing heat output.

Distributing power across more individual diodes improves long-term reliability and produces exceptionally even canopy coverage.

Efficient 320W Performance

Operating at 320 watts, the fixture produces 913 µmol/s PPF with an efficacy rating of 2.85 µmol/J.

This combination delivers professional light intensity while maintaining low electrical consumption.

Optimized for Rectangular Grow Spaces

Unlike square fixtures, the elongated bar layout is engineered specifically for 2' × 4' and 3' × 5' grow tents.

The design improves edge-to-edge coverage and reduces uneven lighting across longer canopies.

Smart WiFi & Bluetooth Control

Integrated Bluetooth and WiFi connectivity allow complete wireless control using the Spider Farmer mobile app.

Growers can remotely adjust brightness, automate lighting schedules, and simulate natural sunrise and sunset cycles.

Full Spectrum Growing

The balanced full spectrum supports healthy vegetative growth, vigorous flowering, and complete seed-to-harvest cultivation.

Its broad white output combined with deep red wavelengths provides lighting suitable for every stage of growth.

Passive Cooling Design

The open aluminum bar frame promotes efficient passive cooling without internal fans.

A removable driver can also be mounted outside the grow tent to reduce heat inside the growing environment.

Daisy Chain Expansion

Compatible fixtures can be connected together for synchronized dimming and centralized control.

This allows multiple lights to operate together through the Spider Farmer control system for larger installations.

Built for 2' × 4' Grow Tents

The G4500 is optimized for rectangular indoor gardens where consistent light distribution is critical.

Its combination of smart controls, efficient performance, and uniform coverage makes it an excellent choice for hobby growers and serious indoor cultivators alike.
