The short answer
The best high bay garage light is the HYPERLITE 150W: 21,750 lumens at 145 lm/W, IP65, UL certified, with a safety rope in the box — and the only fixture here that dims, which matters because 21,750 lumens from one point is too much light for most garages at full output. The CINOTON 160W is brighter at 24,000 lumens and publishes a light-decay figure below 5%, but does not dim. Below a 10-foot ceiling, buy linked shop lights instead.
The brand-name high bay with surge protection and a UV-stable lens. Less efficient and less bright than the imports, with real warranty support behind it.

What a high bay is, and when it is wrong
A UFO high bay is a single round fixture that puts out as much light as five or six 4 ft shop lights. It was designed for warehouses with 20-foot ceilings, which is the key to understanding both why it works in a tall garage and why it fails in a normal one.
The light comes out as a cone. From 20 feet up, that cone has spread wide enough to light a large floor area evenly. From 8 feet up, it is a bright circle directly underneath with dark corners around it — and looking anywhere near it is unpleasant.
Ceiling 12 ft or more — a high bay is the right answer, and one or two fixtures replace an entire run of shop lights with two mounting points instead of twelve.
Ceiling 10 to 12 ft — a high bay works, and dimming stops being optional.
Ceiling under 10 ft — buy linked shop lights. The best LED shop lights covers them, and the flat coverage is genuinely better at that height.

CINOTON wins on raw numbers — 24,000 lumens and 150 lm/W are both the highest here — and it is the only maker publishing a light-decay figure, which is the spec that predicts output in year eight. It is also the fixture most likely to be too bright, because it cannot be turned down.
HYPERLITE gives up 2,250 lumens and 5 lm/W to get dimming, IP65 and UL certification with a safety rope in the box. In a home garage that is the better set of trades, which is why it is the pick.
The two specialist choices
Sylvania 100W is the only brand-name fixture here, and it brings two things nothing else does: 2 kV surge protection, and a UV-stabilized polycarbonate lens that will not yellow where sunlight reaches it through an open door. Surge protection is worth more than it sounds in a garage sharing a circuit with power tools and a compressor. The cost is efficiency — 110 lm/W is the lowest here — and at 11,000 lumens you will want two.
Sunco 150W, 10-pack is a shop-scale purchase rather than a garage one, and it earns its place on one specification: a published operating range of -40F to 113F. In an unheated detached garage in January that figure is the difference between a fixture that starts and one that does not. It is also DLC certified, which is what utility rebate programs require — worth checking your provider before buying ten of anything.
Mounting: the part that is actually dangerous
A high bay is a 7 to 8 lb lump of die-cast aluminum hanging over where your car parks. Three rules.
Use the safety rope if one is supplied. HYPERLITE includes one and Sylvania includes a hook with a safety screw. If your fixture has neither, add an independent safety cable.
Mount to structure, not to drywall. A joist, a purlin or a beam. A ceiling box rated for a light fixture is rated for a light fixture, not for 8 lb on a hook plus a cord.
Check the mounting options before you order. The Sunco supports hook, ceiling and 3/8 in. NPT pole mounting; others are hook only, which assumes you have something to hook onto.
Two of the four here are plug-in — the Sylvania has a 6 ft cord and plug, and the HYPERLITE ships with a 5 ft cord. The other two assume hardwiring. If there is no ceiling outlet, that is an electrician's visit to budget for alongside the fixture.

Where it wins
+Publishes a full operating temperature range (-40°F to 113°F), which matters in an unheated garage in January
+Four named certifications including DLC, which is what utility rebate programs require
+Three mounting options including pole mount
+Ten fixtures: enough for a genuinely large shop
Where it doesn’t
−Non-dimmable, and 195,000 lm across ten fixtures is a vast amount of light to have no control over
−Ten high bays is far more than a home garage needs
−No published weight
What to pair with a high bay
A high bay lights the room and nothing else. It will not light the inside of an engine bay, the underside of a car, or the back of a deep shelf, because all of those are in its own shadow. Every garage with high bays also needs task light.
The HYPERLITE 150W, because it is the only fixture here that dims. In a garage with a 12-foot ceiling, 21,750 lumens from a single point is genuinely too much light without dimming, and it is also IP65, UL certified and ships with a safety rope. Budget separately for a 1-10V dimmer, which is not a standard wall dimmer.
How high does the ceiling need to be for a high bay light?+
Practically, 10 feet and up. A UFO high bay throws a narrow cone of very intense light; mounted at 8 feet it is uncomfortable to stand under and leaves the edges of the bay dark. Below about 10 feet, linked 4 ft or 8 ft shop lights give flatter, more usable coverage — 4 ft versus 8 ft shop lights covers that choice.
How many high bay lights do I need for a garage?+
One per bay as a starting point, because each fixture lights a cone rather than a room. A standard two-car garage with a 12 ft ceiling wants two 150W fixtures placed over the working half of each bay, not one in the center. A single high bay in the middle of a two-car garage leaves both front corners dark.
Are high bay lights dimmable?+
Most are not. Of the four here only the HYPERLITE is, and it uses 1-10V dimming, which requires a compatible dimmer rather than a standard household one. The CINOTON and Sunco fixtures are explicitly non-dimmable, which matters when the output is 24,000 and 19,500 lumens respectively.
What does a light decay figure tell you?+
How bright the fixture still is years from now. CINOTON publishes light decay below 5% — the only maker here that gives a figure at all — which is the spec that separates a fixture still at full output in year eight from one that has quietly lost a third of its light. It is a function of heat dissipation, which is why the housing material matters.
