Who This Is For

  • You are adopting app-based scheduling because manually adjusting your dimmer every day is a task you want to automate
  • You are choosing a bar fixture because your current single-source light leaves the edges of your 2x4 tray underdeveloped

What We Found

  • The bar design puts more light on the edges of a two by four tent compared to a traditional board fixture.
  • Mounting the driver outside the tent is the most effective way to drop the temperature by a few degrees instantly.

What Users Say

  • Users who switched to the app say they stopped checking their timers manually after setting the digital schedule.
  • Growers using rectangular tents report that their edge plants finally match the height of the ones in the center.

Spider Farmer SE4500 Smart LED Grow Light | Bluetooth & WiFi Control

Looking to maximize lighting efficiency in wider rectangular growing areas with professional smart control capabilities?

The Spider Farmer SE4500 delivers optimized full spectrum lighting designed specifically for 2'x4' grow tents and rectangular growing spaces up to 3'x5' maximum coverage, providing the same exceptional performance growers have trusted for years.

This latest version features Bluetooth & WiFi connectivity with upgraded digital precision dimmer control, enabling complete remote management through the Spider Farmer app for automated scheduling and monitoring.

This advanced lighting system generates 913 μmol/S PPF with an efficient 2.85 μmol/J rating while consuming 320 watts. Due to Samsung's exit from the LED chip market, Spider Farmer engineered a comprehensive upgrade featuring high-performance Bridgelux diodes with increased diode count, maintaining all key performance specifications for the same reliable growing results. The 3-bar design ensures even plants on the outer edges receive ample light coverage with deeper penetration.

The innovative passive cooling system utilizes aluminum bar construction that allows air to efficiently circulate through the grow light, maintaining optimal operating temperatures without noisy fans. The detachable driver can be mounted remotely to further reduce heat in your growing area.

Built with water-resistant diode coating to prevent moisture damage and backed by a comprehensive 5-year warranty, this fixture provides reliable performance for professional growing operations. The integrated smart controls enable precise dimming and scheduling via smartphone app for customized growth optimization.
