Smart Control through the Spider Farmer App
(Sensor required)
Real-time PPFD Display
PPFD Mode: Set a target PPFD value — the light will automatically adjust brightness to maintain it.
Timer Mode: Set light on/off time and target brightness.
Go Dark: Set a target temperature — when reached, the light dims to 11%.
Turn Off Light: Set a target temperature — when reached, the light turns off automatically.
Mimics natural sunrise and sunset to reduce plant stress and promote healthier growth.
e.g. : Start time: 8:00 AM; End time: 8:00 PM; Simulation time: 30 minutes
→ From 8:00–8:30 AM, brightness gradually increases to the target level
→ From 7:30–8:00 PM, brightness slowly dims until the light turns off
Why the Update & What’s Changed in 2026 Version？
Following Samsung’s strategic adjustment in its LED chip portfolio, the SE Series has been engineering-upgraded. Change to advanced Bridgelux High-Efficiency LED Platform
The new version features high-performance LEDs with an increased diode count, ensuring that light efficacy, PPF output, and light uniformity remain consistent with the previous Samsung-based version. All key performance specifications are maintained to deliver the same reliable growing results.
Energy Efficient & Cost-Saving：With only 320W power consumption, the SE4500 uses significantly less electricity than traditional HPS grow lights, helping reduce energy bills and operating costs.
High Efficacy & Uniform Lighting: SE4500 320W LED grow light designed with 3 LED bars to provide more even canopy coverage, especially to the outer edges of cultivation areas. Achieving an impressive PPE of 2.85 umol/J. For 70x140cm Grow Tent, 4-Inch Inline Fan.
Optimized Light Spectrum: with Spetrum 660-665nm,2800–3200K,4800-5000K, which supports all stages of plant growth, from seedling to flowering. The dimming knob is ideal for growers to adjust the light intensity according to different growing stages.
Efficient Cooling: Bar light design and aluminium material on the back contribute to better airflow and great heat dissipation. Reducing the risk of heat damage to plants and allowing for closer placement to the canopy without causing burning. Efficient light output and lower heat can lead to faster growth cycles and quicker harvests.
Daisy Chain Dimming: The dimming knob is ideal for growers to adjust the light intensity according to different growing stages.
The daisy-chain function allows you to connect up to 50xSE4500 indoor plant led grow light – dimming multiple lights simultaneously. Widely applied in the commercial growing (horizontal and vertical), grow rooms, home grows, grow tents, hydroponics.

Upgraded from a 2x2x4 tent and a SF1000 + glow 30 to 4x2x6 tent and a SF4500 light. Just harvested first grow, still drying so no yield weight yet, but it’s will be good. My girls loved this light, never had it over 70% the entire grow, due to heat at the upper parts of the tent. Had a new 4″ exhaust fan in with it, so for the next grow, adding a 6″ exhaust, will use the 4″ for intake air. Had to learn not to put it on 100%, especially for germination. Accidently killed a couple of seedlings with the light too high. Never moved the light, stayed at the top of the tent the whole grow. Wall to wall coverage, no need for side or under canopy lights, this one is strong enough to get to all the buds.
Over thirty years I have been using 1000w MH and 1000w HPS waiting for LED companies to mature to produce units and the realistic data to back up their claims. 2022 I pulled down the old tech and up with a Spider Farmer SE 7000(8 bar). The heat problems of summer growing and buds bumping hot bulbs are no more. Better light coverage and no hot spots. 2024 I added a SF SE 4500. I’m happy and my girls are happy.
I have now been using it for a year in my 2×4 tent with amazing results. The light output is way beyond anything I had expected. Amazing wall to wall coverage with my plants absolutely loving it. This light is why I now use Spider Farmer exclusively.
