The short answer
For ceilings above roughly 15 to 20 feet, an LED highbay usually beats an LED tube retrofit. A highbay like the Challenger 5 delivers 26,000 to 42,000 lumens from a single sealed fixture, while a typical 4-foot LED tube delivers about 2,000 to 2,200 lumens. That means fewer fixtures, fewer failure points and optics built to push light to the floor. LED tubes still make sense for low ceilings, offices and quick, low-budget swaps where the existing fixtures are in good shape.
LED highbay vs LED tube: what’s the difference?
An LED tube is a lamp that slides into an existing fluorescent fixture. An LED highbay is a complete, purpose-built fixture with its own driver, heat sink and optics, designed to be mounted high and throw light down to the work floor.
LED tubes come in four installation types:
- Type A (plug-and-play) runs on the existing fluorescent ballast. It’s the fastest swap, but the old ballast stays in the circuit and must be compatible.
- Type B (ballast bypass) wires directly to line voltage after the ballast is removed. It’s more efficient but requires rewiring, and UL requires a warning label on the fixture afterward.
- Type C uses a separate external LED driver. It performs well but costs more and is more complex to install.
- Type A+B (hybrid) can run on a compatible ballast or be converted to ballast bypass later.
Every tube option keeps the old fixture housing, sockets and lens. A highbay replaces all of it.
Pros and cons: LED highbay vs LED tubes
Highbays win on output, efficiency, lifespan and durability. Tubes win on upfront cost and speed of install in low, clean spaces.
| Factor | LED highbay (Challenger 5) | Typical 4-ft LED tube |
|---|---|---|
| Light output | 26,000–42,000 lumens per fixture | 2,000–2,200 lumens per tube |
| Lamps to reach 26,000 lumens | 1 fixture | About 12 tubes |
| Efficacy | 170 lumens per watt | About 133 lumens per watt |
| Rated life | 200,000+ hours with controls* | 50,000 hours |
| Heat rating | Up to 65°C / 149°F ambient | Check the tube’s ambient temperature rating |
| Moisture and dust | IP65 sealed | Typically damp-location rated |
| Surge protection | 10 kV | Varies by product |
| Optics | Standard, narrow and wide, with rotating light bars | Fixed; depends on the old fixture’s reflector |
| Built-in controls | Occupancy sensor for mounts up to 60 ft, network-ready | Usually separate sensors; many tubes aren’t dimmable |
| Existing ballast | Removed with the old fixture | Type A keeps it in the circuit |
| Upfront cost | Higher per fixture | Lower per lamp |
| Install | New fixture, one connection | Fast swap (Type A) or rewire (Type B) |
Highbay specs are from the EDE Challenger 5 performance report. Tube specs reflect typical DLC-listed 4-foot T8 LED tubes. *Performance ratings depend on configuration, controls, installation conditions and manufacturer requirements.
When LED tubes still make sense: low ceilings, offices and break rooms, fixtures with healthy ballasts, and short-term budgets where a quick swap beats a full fixture replacement.
Power-selectable highbays: the right light level from one fixture
A power-selectable (wattage-selectable) highbay has a switch that sets the fixture to one of several wattages. You pick the output that fits the space instead of buying a different fixture for every area.
EDE’s current highbays are power-tunable in three steps:
| Fixture | Lumens at full power | Selectable wattages |
|---|---|---|
| 100W highbay | 20,000 | 60W / 80W / 100W |
| 200W highbay | 40,000 | 130W / 165W / 200W |
Why it matters in a plant:
- Stop over-lighting. Dropping a 100W fixture to 60W cuts that fixture’s power by 40% in areas that don’t need full output.
- It’s high-end trim built into the fixture. Consumers Energy credits high-end trim with 5–19% savings (Consumers Energy NLC flyer).
- It can count toward the rebate. DTE’s Tier 1 NLC rebate lets a permanently trimmed wattage be used as the post-upgrade wattage, with photos or power measurements as proof (DTE rebate catalog).
- Fewer SKUs on the shelf. One fixture covers different mounting heights, aisles and open floor, so maintenance stocks less spare inventory.
- Easy to change later. When a line moves or racking changes, reset the wattage instead of replacing the fixture.
The Challenger 5 highbay: built for heat where other LEDs fail
The Challenger 5 is the highbay EDE installs where standard LED fixtures have burned out. It’s rated for ambient temperatures up to 65°C / 149°F, and EDE has it running in a Michigan manufacturing facility today.
Heat is what kills most industrial LEDs. High ceilings over furnaces, ovens, molding presses and process lines stress drivers, cause lumen loss and lead to early failure. The Challenger is designed around that problem:
- Heavy-duty aluminum housing pulls heat away from the LEDs and driver.
- Temperature throttling lowers fixture power during extreme conditions to protect the electronics.
- IP65 sealing resists water, moisture, dust and debris, including many dirty, humid and wash-down areas.
- 10 kV surge protection and a serviceable driver protect against the electrical noise common in plants.

Add networked lighting controls for the biggest savings
Switching to LED is step one. Consumers Energy says switching to LEDs alone can reduce an electric bill by up to 50%, and lighting makes up about 36% of a facility’s electric bill (Consumers Energy NLC flyer). Networked lighting controls capture what’s left.
Consumers Energy’s program data shows:
- 47% estimated average energy savings from networked lighting control systems (DesignLights Consortium).
- 70% of NLC projects generated 30% or more in energy savings.
- 70–99% total potential savings when LEDs and controls are combined (DNV GL study).
Savings by control strategy, per Consumers Energy:
| Control strategy | Typical savings |
|---|---|
| Daylight harvesting | 10–60% |
| Occupancy / vacancy sensing | 15–30% |
| Time scheduling | 10–30% |
| Personal controls | 10–30% |
| High-end trim | 5–19% |
A highbay with a built-in occupancy sensor, network compatibility and selectable wattage covers three of those strategies in one fixture. That’s the advantage a tube retrofit can’t match without adding separate sensors and controls.

Frequently asked questions
Are LED highbays better than LED tubes?
In high-ceiling plants and warehouses, usually yes. A highbay delivers far more light per fixture, higher efficacy and a longer rated life, and it replaces the old ballast and housing entirely. LED tubes are better suited to low ceilings and quick, low-cost swaps.
How many LED tubes equal one highbay?
A 4-foot LED tube produces about 2,000–2,200 lumens. Matching a 26,000-lumen highbay takes about 12 tubes, plus the fixtures and ballasts or rewiring to run them.
What is a power-selectable highbay?
It’s a highbay with a switch that sets the fixture to one of several wattages. For example, a 100W highbay can run at 60W, 80W or 100W. It lets one fixture fit different areas and acts as built-in high-end trim.
What LED highbay works in high-heat areas?
Look for a fixture rated for high ambient temperatures with a heavy heat sink. The Challenger 5 is rated up to 65°C / 149°F and uses temperature throttling to protect its electronics.
Should I use Type A or Type B LED tubes?
Type A is faster and needs no rewiring, but depends on a compatible ballast that can still fail. Type B removes the ballast for better efficiency and reliability, but needs rewiring and a UL warning label.
Do LED highbays qualify for rebates in Michigan?
Yes. Consumers Energy and DTE Energy both offer business incentives for DLC-listed LED fixtures and networked lighting controls. EDE confirms current eligibility and handles the paperwork.
