7 Best LED Grow Light Strips in 2026

Updated for 2026 — This article has been reviewed and updated with the latest recommendations.

LED grow light strips fill a niche that standard overhead panels cannot: they deliver light to the sides and lower canopy of cannabis plants where shadows typically rob you of bud development. Side lighting with LED strips supplements your main light, improving overall yield by fattening up lower branches that would otherwise produce small, airy buds.

Here are the best LED grow light strips for cannabis in 2026.

Best LED Grow Light Strips Compared

1.

Barrina T5 Grow Light Strips (6-Pack)

Barrina's T5 strips are the most popular budget LED strips for cannabis growing. A 6-pack of 2-foot strips provides enough coverage to line the sides of a 4x4 or 4x2 tent. Each strip draws 22 watts and produces a full-spectrum white light with enhanced red wavelengths for flowering support.

The strips connect end-to-end with included linking cables, and they mount with simple clips.

The daisy-chain design means one power cord runs the whole setup. At $30-40 for six strips, the cost per watt of supplemental light is extremely low.

These are not powerful enough to use as primary lights, but as side lighting to supplement a quality overhead LED panel, they make a noticeable difference in lower bud development and overall yield.

2. HLG Sidelight

Horticulture Lighting Group (HLG) brings their premium Samsung diode technology to a compact side light strip.

The 18-inch bar uses Samsung LM301H EVO diodes, which are among the most efficient LEDs in horticulture. At 20 watts, it produces more usable light per watt than any other strip on this list.

The build quality is excellent with a solid aluminum heatsink and quality driver. It mounts vertically on tent poles or walls with the included brackets. At $50-65 per bar, it is the most expensive per-unit option, but the light quality and efficiency justify the premium for growers who want the best.

Spider Farmer SF Side Light Bar

Spider Farmer's side light bar draws 40 watts and provides meaningful supplemental light in a 3-foot form factor. It uses Samsung LM301B diodes, which are efficient and proven. The bar mounts vertically alongside plants in a tent to illuminate the lower canopy.

The included dimmer allows you to dial in the exact intensity you need. At $45-60, it sits between the budget Barrinas and the premium HLG, offering a good balance of quality and value.

Two bars on opposite sides of a 4x4 tent provide excellent supplemental coverage.

4. Monios-L T5 LED Grow Light (4-Pack)

Monios-L strips are particularly good for seedlings, clones, and early vegetative growth. The full-spectrum output is gentle enough for young plants that cannot handle intense overhead lighting.

Each 2-foot strip draws 20 watts and links together for continuous coverage.

They also work well as side lights in flower, though the lower wattage means they contribute less than the Barrina or Spider Farmer options. At $35-45 for a 4-pack, they are a versatile investment that serves multiple purposes in a grow room.

5. Feit Electric 2ft LED Grow Light

Feit Electric strips are available at Home Depot, Lowes, and most hardware stores, making them the easiest option to buy in person. The 19-watt strip produces a balanced full-spectrum light suitable for growing. It includes mounting hardware and a standard plug with an on/off switch.

The simplicity is the selling point. No linking, no dimmer, no app. Just plug it in, mount it, and let it run. At $20-28 per strip, it is affordable and accessible. Pick up a few on your next hardware store run to supplement your tent lighting.

Placement Tips for Side Lighting

Mount side light strips vertically at canopy height, positioned to illuminate the lower third of your plants where overhead light struggles to penetrate. Keep strips 6-12 inches from the nearest foliage. Run side lights on the same timer as your main overhead light to maintain consistent photoperiods. For flowering plants in a 4x4 tent, 2-4 side light strips adding 40-100 total watts of supplemental light can increase overall yield by 10-20% by fattening up lower buds that would otherwise stay small and airy.
