Built for larger commercial grow rooms, this 8ft under canopy LED grow light covers more canopy per fixture than shorter options, cutting down on the number of units needed to light a long row. Available in both dual side (180°) and triple side (270°) emission, at a fixed 250W, this 8ft under canopy lighting option is sized for growers running longer benches and wider rows. Built with the same high efficacy Samsung LED chips, red-dominant spectrum, and IP65 waterproof housing as the rest of our under canopy lighting line, and clients running this size report the same consistent 20% to 25% yield increase.
As an under canopy LED grow light manufacturer, we support direct under canopy LED grow light wholesale orders for growers scaling up to this size across multiple rooms.
Products Detail
Fewer Fixtures for Large Grow Rooms
Longer rows mean more connection points - every fixture needs a daisy chain link and eventually a power source. This 8ft under canopy LED grow light covers the same row length with fewer total units than a 6ft setup, and sized for the longer benches and wider rows common in large scale operations, it means fewer daisy chain connections, fewer bracket installs, and less cable across a big room - real time saved on install for growers scaling up under canopy lighting for large canopy rows.

Understanding Dual vs Triple Design
The structural difference between dual and triple emission comes down to how many LED strips are built into the housing itself.
Dual Side
The housing carries two parallel LED strips, positioned symmetrically along the board - one on each side. This two-strip layout is what produces the 180° emission pattern, with light directed from two opposing faces of the fixture.
Triple Side
The housing is built wider to fit a third LED strip alongside the original two, adding an extra emission channel across the same board length. That third strip is what extends coverage to 270°, pushing light out from three directions instead of two.
The easiest way to tell them apart
On the production floor, it comes down to counting strips: two rows of LEDs mean a dual unit, three rows mean a triple unit. The triple version's housing is also visibly wider to accommodate the added strip, which is why the bracket height range differs slightly between the two - 22cm to 38cm for dual, 22cm to 32cm for triple.
Certification
who we are?
For 10 years, JT Grow Light has built LED grow light solutions for growers across 40+ countries, backed by a factory that handles the full process in house - automatic SMT assembly, automatic screwdriver assembly, and every fixture tested through optoelectronic, aging, and PPFD testing before it ships.
We maintain complete qualifications and full specification coverage across our product line, with certifications including CE, FCC, and IP66. OEM/ODM production is also available for growers and distributors who need customized builds.
FAQ
Q: Why choose 8ft over 6ft for large grow rooms?
A: An 8ft fixture covers more row length per unit than a 6ft fixture, so a large room needs fewer total fixtures - fewer daisy chain connections and less cable across a long bench.
Q: What's the physical difference between dual side and tripe side housing?
A: Dual side housing carries two LED strips for two-direction emission. Tripe side housing carries three strips, adding a third emission channel and a slightly wider fixture body.
Q: How many 8ft units can I daisy chain on one power cord?
A: Up to 5 units can be daisy chained together on a single power cord, same as the 6ft version.
Q: Is the bracket different between dual side and tripe side versions?
A: Yes - dual side units use a black bracket adjustable from 22cm to 38cm, while tripe side units use a white bracket adjustable from 22cm to 32cm.
