Who This Is For
- You are switching to narrow profile bars because your current wide fixtures block too much natural sunlight.
- You are simplifying your electrical layout because wiring dozens of individual drivers is taking too long to install.
What We Found
- The slim 3-inch width is why this bar vanishes in a greenhouse once it is mounted high in the rafters.
- We recommend these over 720W panels when you need intensity but have a layout that makes bulky squares a nuisance.
What Users Say
- Operators who switched to the daisy chain setup say the reduced cabling made overhead space easier to manage.
- Users who replaced HPS units say the 2.9 efficacy rating translated to a noticeable drop in monthly cooling costs.
TotalGrow High Intensity Top-Light 660W Bar LED Grow Light
Struggling with excessive shadowing and inefficient energy consumption in your commercial greenhouse? The TotalGrow High Intensity Top-Light 660W Bar offers a powerful, streamlined solution designed to maximize photosynthetic light while minimizing the footprint in your growing space.
As a higher-output alternative to the TotalGrow 345W High Intensity Top-Light, this fixture delivers exceptional efficacy for commercial cultivation. Whether you are a greenhouse grower or an indoor cultivator, this 660W powerhouse provides up to 1865 μmol/s of light output with efficacy ratings reaching 2.9 μmol/J in the high-efficiency model.
The narrow-profile body (43" x 3" x 4") is engineered to create minimal shadows in greenhouse applications. For streamlined installations, the daisy-chain capability allows you to connect up to 4 units on 240V systems, significantly reducing electrical complexity and setup costs. Built to IP66 waterproof standards with ETL and DLC certifications, this fixture ensures reliable performance in high-humidity environments for over 50,000 hours.

Applications
The TotalGrow HI-Top light bar is specifically engineered for commercial cultivation environments, including:
- Greenhouse supplemental lighting where minimal shadowing is essential, often enhanced with dedicated TotalGrow UCL 150W under canopy lights to illuminate lower growth.
- Indoor commercial grow operations requiring high light intensity, providing performance comparable to the TotalGrow MH Lumit 720W.
- Multi-tier cultivation systems with space constraints, where a leaner fixture like the TotalGrow Mezzo 100W light bar or a TotalGrow Stratum 10 clone light might be suitable.
- Research facilities requiring precise light control, a feature perfected in models like the TotalGrow Solark KC 250W or the high-output TotalGrow Solark KC 1000W.
