LED High Bay vs Linear High Bay: A Comparative Buying Guide

Facility managers who evaluate commercial LED lighting suppliers for warehouse or factory projects usually need to choose between two common high-bay formats: a round UFO LED high bay light and an elongated LED linear high bay light. This guide compares the HL-E01 UFO LED high bay light with the SH-E01 LED linear high bay light using verified product specifications from Zhejiang Lepeng Electric Appliance Co., Ltd. The focus is on form factor, power options, efficiency, beam angle, protection, mounting method, and warranty.

Zhejiang Lepeng Electric Appliance Co., Ltd. is a manufacturer of LED lamps and LED luminaires established in 2009. The company operates three production bases, with its headquarters in Shangyu, Zhejiang, and additional bases in Qiandaohu, Zhejiang and Jingdezhen, Jiangxi. Its total factory area covers 200,000 square meters, and it employs approximately 2,000 staff, including an R&D team of 200 professionals. Around 90% of its output is exported to markets such as the EU, Southeast Asia, the Middle East, and Latin America. The company’s own brand, MKOPTO, has gained recognition in global lighting markets.

Why the UFO vs Linear Decision Is Not Only About Shape

The practical problem for many buyers is that two high bay lights may look similar in energy performance but still require different installation and environmental checks. The HL-E01 and SH-E01 are both commercial LED high bay products, but their verified specification sheets differ in several important areas.

Buyers should not choose a high bay simply because one is labeled “round” and the other is labeled “linear.” The more useful comparison is based on power range, mounting options, IP protection, optical beam data, warranty terms, and the electrical components listed in the product specification.

Industry Background

The LED lighting market is large and continues to be an important category for commercial and industrial buyers. According to Fortune Business Insights, the global LED lighting market was valued at USD 109.11 billion in 2025 and is projected to reach USD 336.90 billion by 2034. According to Grand View Research, the global commercial lighting market was estimated at USD 47.54 billion in 2024, with LED products holding a 58.1% revenue share. This context matters because energy efficiency and product lifetime are often central to high bay replacement decisions in warehouses and factories.

There is also a supply-side consideration. According to data published by OEC, China exported USD 31.4 billion in light fixtures in 2024, representing 59.3% of total global exports. A buyer searching for commercial LED lighting suppliers may therefore encounter many manufacturers from the same region. In that situation, verified product specifications become the main way to distinguish between similar-looking fixtures.

Detailed Solution: Comparing the HL-E01 and SH-E01

What Is the HL-E01 UFO LED High Bay Light?

The HL-E01 is a UFO LED high bay light designed for industrial and commercial use. Its verified applications include warehouses, factories, retail spaces, and gyms. The fixture uses a die-cast aluminum body with a PC lens, and the housing structure is described as a die-cast aluminum body with a hollow heat dissipation structure.

Power options are 100W, 150W, 200W, and 240W. Rated voltage is listed as 185-265V or 100-265V. Efficiency ratings are 140, 160, 185, and 210 lm/W. Color temperature options are 4000K, 5000K, and 6500K. Surge protection is 6KV/6KV. The cable is 3x1.0mm² with 300mm exposed leads, pre-wired to the power supply. The power supplies are from Sosen and Moso. The HL-E01 also supports optional motion sensor compatibility with a smooth 3-second brightness transition.

What Is the SH-E01 LED Linear High Bay Light?

The SH-E01 is an LED linear high bay light designed for warehouses, factories, and workshops. It is explicitly described as suitable for harsh industrial environments. The product has an IP65 rating, meaning it is rated for protection against dust and water, and the product carries a 5-year warranty.

The housing is made of aluminum alloy with a PC/PMMA lens. Power options are 50W, 100W, 150W, and 200W. Luminous efficacy ratings are 100, 135, or 150 lm/W depending on configuration. The beam angle is 90° in the horizontal direction and 120° in the vertical direction. Color temperature options are 3000K, 4000K, 5000K, and 6500K. Available dimensions are 305.6×97.3×68.1mm, 580.6×97.3×68.1mm, and 855.6×97.3×68.1mm.

Power Options and Efficiency

For buyers who need a wider top-end wattage, the HL-E01 reaches 240W, while the SH-E01 starts at 50W and reaches 200W. This can matter when a project has very high mounting points or when the lighting design plan calls for fewer, higher-wattage fixtures.

The HL-E01 lists efficiency ratings of 140, 160, 185, and 210 lm/W. The SH-E01 lists efficiency ratings of 100, 135, and 150 lm/W. These numbers should be checked against the specific catalogue configuration because efficiency can vary by driver, color temperature, and power setting. The available color temperatures also differ: the SH-E01 includes 3000K as an option, while the HL-E01 offers 4000K, 5000K, and 6500K.

Beam Angle and Light Distribution

Beam angle is necessary for planning fixture spacing and uniformity. In the verified product data, the SH-E01 has a clearly listed beam angle of 90° horizontally and 120° vertically. This is a wide beam specification intended for broad-area indoor coverage in applications such as warehouses, factories, and workshops.

The HL-E01 product specification included in this comparison does not list a beam angle. Because a UFO-style fixture can be ordered with different optics, a buyer should request the photometric file and exact beam angle from the supplier before completing the mounting layout.

Protection Rating

IP protection is one of the clearest differentiators between the two models. The SH-E01 has an IP65 rating and is positioned for use in harsh industrial environments. The HL-E01 is a UFO LED high bay light intended for warehouses, factories, retail spaces, and gyms, but its verified specification sheet does not list an IP rating.

If the installation area is dusty, exposed to water spray, or subject to routine cleaning, the safer route is to use the linear SH-E01 because its IP65 rating is explicitly stated. If the project requires a high-wattage UFO fixture in a cleaner indoor space, the HL-E01 may be the relevant model, but the buyer should confirm the absence of an IP rating or request the specific IP test documentation.

Mounting and Wiring

Mounting method is another practical difference. The SH-E01 can be installed in two ways: with a mounting kit for surface installation, or with chain/cable suspension. The SH-E01 also uses a one-piece connector design, which is described in the verified product data as an advantage for installation speed.

The HL-E01 specification does not describe a surface mounting kit or suspension hardware in the available product facts. The HL-E01 cable is specified as 3x1.0mm² with 300mm exposed leads, pre-wired to the power supply. Buyers planning to hang the HL-E01 should verify which mounting brackets, hooks, or suspension accessories are recommended before ordering.

Warranty and Electrical Protection

Warranty terms can affect the total cost of ownership after installation. The SH-E01 has a stated 5-year warranty. The HL-E01 specification in this comparison does not include a warranty period, so warranty coverage should be confirmed directly with the supplier.

The HL-E01 provides 6KV/6KV surge protection and lists Sosen and Moso power supplies in its verified product specification. The SH-E01 specification does not list surge protection in the available data. For buyers in facilities with unstable electrical conditions, these differences should be reviewed during the specification stage.

Summary of the Two Product Categories

The HL-E01 is best understood as a UFO LED high bay light with a die-cast aluminum housing, high wattage options, high published efficacy, and 6KV surge protection. The SH-E01 is best understood as a linear LED high bay light with an aluminum alloy housing, IP65 protection, a 5-year warranty, and a clearly listed wide beam angle. Neither model replaces the other unless the application conditions are fully compared.

Step-by-Step Selection Process

1. Confirm the indoor application. Determine whether the space is a warehouse, factory, workshop, retail space, or gym. The HL-E01 is listed for warehouses, factories, retail spaces, and gyms. The SH-E01 is listed for warehouses, factories, and workshops.
2. Check the environment. If the environment is described as dusty, wet, or harsh, look for an explicit IP rating. Among the two models with available verified data, only the SH-E01 has an IP65 rating.
3. Compare wattage ranges. The HL-E01 covers 100W to 240W. The SH-E01 covers 50W to 200W. Match the fixture wattage to the lighting layout rather than to the shape of the housing.
4. Request beam angle data. The SH-E01 has published a 90°(H) × 120°(V) beam angle. If a UFO fixture such as the HL-E01 is preferred, request the exact beam angle and photometric file because it is not listed in the available specification.
5. Review mounting conditions. The SH-E01 offers surface installation with a mounting kit or chain/cable suspension. For the HL-E01, confirm the approved mounting bracket with the supplier before ordering.
6. Check electrical compatibility. Compare voltage, cable form, surge protection, and driver brand. The HL-E01 lists 185-265V or 100-265V input, 6KV/6KV surge protection, and Sosen and Moso power supplies.
7. Review warranty terms. The SH-E01 lists a 5-year warranty. If the HL-E01 is chosen, request the warranty period in writing.
8. Request a sample or pilot unit. Before large-volume procurement, test the selected fixture at the actual mounting height and compare it with the photometric plan.

Use Cases

Warehouse or Factory with a Strict Dust and Water Specification

If a buyer needs a fixture that is expressly rated for harsh industrial environments, the SH-E01 is the model with an explicit IP65 rating and a 5-year warranty. Its housing is aluminum alloy with a PC/PMMA lens, and its listed applications include warehouses, factories, and workshops.

Retail Space, Gym, or Industrial Space Needing a High-Wattage UFO Fixture

The HL-E01 is listed for warehouses, factories, retail spaces, and gyms. It offers 240W as the highest available power setting, published efficiency ratings up to 210 lm/W, and a die-cast aluminum body with a hollow heat dissipation structure. This makes it a practical model for buyers who want a round, compact high bay with high wattage and who have confirmed the installation method separately.

Higher-Ceiling Projects Needing Broad-Area Coverage

The SH-E01’s beam angle is clearly verified as 90° in the horizontal direction and 120° in the vertical direction. That wide beam specification can be used in a lighting layout for large indoor areas where the fixture is mounted above a wide floor plane.
