Who This Is For
- You are installing intercanopy lighting because shaded lower leaves keep your plant material from ripening evenly.
- You are adding greenhouse supplemental light because bulky fixtures cast too much shadow and create uneven growth.
What We Found
- The two-inch height is a real winner for vertical racks where every inch of clearance affects plant health
- Most 100W bars feel heavy, but this four-pound unit is light enough to hang without stressing thin rack frames
What Users Say
- Users who swapped out standard clone bars say the extra intensity noticeably improved vigor in the early stages
- Growers who mounted these as side lighting report that lower crop material stays healthy right until harvest
TotalGrow Mezzo 100W 44" LED Grow Light Bar
Struggling with uneven light distribution or shaded lower leaves in your grow space? The TotalGrow Mezzo 100W 44" Light Bar is the versatile, high-efficiency solution designed to deliver precision illumination in greenhouses and indoor environments. It serves as a high-output upgrade from standard clone LED light bars, ensuring every plant receives the energy it needs to thrive.
Producing a powerful 277 µmol/s output with an industry-leading 2.8 µmol/J efficacy, the Mezzo 100W maximizes growth while keeping energy costs low. Its ultra-slim profile—measuring just 2 inches tall—prevents significant shadowing in greenhouse applications, making it an ideal companion to the more powerful TotalGrow High Intensity 660W LED for comprehensive commercial coverage.
Installation is effortless thanks to its lightweight 4-pound design and daisy-chain capability, allowing you to connect up to 10 units on a single 120V circuit. For specialized spectral needs, this light bar pairs perfectly with supplemental fixtures like the TotalGrow UVA 30W bar or the Deep Red Grow-Booster. If your application requires multi-channel spectrum control, the TotalGrow Solark KC 250W is an excellent companion fixture.
