COB vs LED Work Lights

The short answer

The query that brings most people here is some form of "is COB better than LED", and the honest answer is that the question contains a category error worth untangling before anything else.

What COB actually means

A conventional LED is one semiconductor die in its own package, with its own lens and its own electrical contacts, soldered to a circuit board. A COB array skips the individual packaging: the bare dies are bonded directly onto a shared substrate, sat close together, and covered with one continuous phosphor layer. Where a conventional emitter is a point of light, a COB array is a lit rectangle.

You will also see SMD on work-light packaging. SMD — surface-mounted device — is the conventional arrangement: individually packaged emitters placed on a board, usually in a visible grid of dots. COB versus SMD is the comparison people actually mean when they write COB versus LED, and both are LED.

Why COB is cheap, and what the cheapness costs

Packaging each die individually is most of the cost of an LED. Skip it and you can put a great deal of light on a board for very little money, which is why COB panels dominate the bottom of the work-light market and why the lumens-per-dollar column on this page reads the way it does. The NEBO BIG LARRY 3 publishes 600 COB lumens for about the price of two coffees.

Two things are given up for that, and both are visible in use rather than subtle.

The first is reach. A large emitting surface cannot be collimated into a tight beam — the optics have nothing small to focus — so a COB panel throws a wide, short-range flood no matter what you put in front of it. NEBO publishes 70 meters for the OMNI 2K at 2,000 lumens; the same brand's SLYDE KING 4K publishes 350 meters from its conventional LED at 4,000. Twice the lumens, five times the distance, same manufacturer, same page.

The second is color. COB arrays are phosphor-converted for output rather than fidelity, and their color rendering is poor as a class. The telling detail is not that the CRI is low; it is that almost no COB product publishes a CRI figure at all. Neither NEBO product on this page publishes one. Streamlight publishes 90 CRI at 4,000K for the FlipMate's second emitter set and 90 CRI for the Syclone's flood, and prints the figure where you can read it.

Prices pulled October 18, 2026. Lumens per dollar is the manufacturer's published maximum output divided by that price, recomputed every time the price moves.

What each one is for

• Lighting a whole garage bay, a campsite or a room in an outage: COB, every time. It is the cheapest wide light there is, and the soft shadows are an advantage when you are moving around under it.
• Working on something at arm's length where color is information — wiring, paint, a leak, bodywork, a wound: a 90-CRI LED. Under a low-CRI panel red wire and brown wire look like the same wire, and no amount of lumens fixes that.
• Seeing to the end of a yard, finding a dog in a field, checking a tree line: a conventional LED with a published beam distance. A COB panel simply cannot do this job.
• One light that has to do all three: a hybrid. The NEBO SLYDE KING 4K carries a zoomable 4,000-lumen LED at one end and a 1,000-lumen COB panel at the other, with a published runtime for each.

1. Most COB lumens per dollar

NEBO OMNI 2K

Lumens per dollar

57

Two thousand lumens of COB flood with a published runtime for all six modes, a 4,000 mAh pack that will also charge a phone, and magnetic handles that let it hang anywhere. What it does not have is a numbered water rating, and COB panels render color poorly as a class.

Max output

2,000 lm

Runtime

1.3 h

Battery

Sealed

Water rating

None published

What it gets right

• A runtime published beside every one of the six modes, which is more than most work lights manage
• Two thousand lumens of flood for the price of a tank of gas
• Rotating magnetic handles, so it hangs or stands wherever there is steel
• The 4,000 mAh pack doubles as a phone charger in an outage

What it gets wrong

• No IP figure at all — 'water-resistant' is a word, not a rating
• Built-in pack, so the light is refuse when the cell is
• COB panels have poor color rendering as a class, and NEBO publishes no CRI figure
• 1.3 hours at full output is a short evening

2. Best light with both an LED spot and a COB panel

NEBO SLYDE KING 4K

Lumens per dollar

53

One body, two emitters: a 4,000-lumen zoomable LED at one end of the slide and a 1,000-lumen COB work light at the other, each with its own published runtime. It is the cheapest way to stop choosing between throw and flood, and the clearest demonstration of what each emitter is actually for.

Max output

4,000 lm

Runtime

1 h

Battery

Sealed

Water rating

IPX7

What it gets right

• A spot and a flood in one body, each with a published runtime
• IPX7 with the depth and duration stated, which the OMNI 2K does not have
• Twenty-four hours on the 100-lumen work mode is a genuinely useful number
• Magnetic base and a red task mode that runs 35 hours

What it gets wrong

• NEBO does not say whether the 20650 cell can be replaced, so we score it as if it cannot
• One hour at 4,000 lumens, and no sustained figure between that and the 400-lumen low
• 1.1 lb and eight inches — this is a toolbox light, not a pocket light
• No CRI published for either emitter

Published specification

• Flashlight, high: 4,000 lumens, 1 hour, 350 m — NEBO published specification

3. Best cheap magnetic work light

NEBO BIG LARRY 3

Lumens per dollar

50

A 600-lumen COB panel, a 220-lumen spot and a red task mode, on three AA cells, with a magnet strong enough to hold it under a hood. It is the least glamorous light here and it is the one that gets used most.

Max output

600 lm

Water rating

None published

What it gets right

• A flood panel is the right shape of light for working on something close up
• AA cells, so it survives a year in a toolbox and still lights
• The magnet is strong enough to matter

What it gets wrong

• NEBO publishes no runtime and no water rating for this model
• COB panels have poor color rendering as a class
• Not rechargeable, so the running cost is AA cells

Published specification

• COB work light: 600 lumens high / 150 lumens low — NEBO published specification
• Spot flashlight: 220 lumens high / 60 lumens low — NEBO published specification
• Red task light: 40 lumens high / 12 lumens low — NEBO published specification
• Battery: 3 x AA (included) — NEBO published specification
• Weight: 0.42 lb — NEBO published specification
• Fittings: Magnetic base, steel belt clip, wall-mount hole — NEBO published specification

4. Best work light with a 90 CRI flood

Streamlight Syclone

Lumens per dollar

7

Four hundred lumens of spot for two hours or 300 lumens of 90-CRI flood for the same, in a 5.3-ounce body that clips, magnets and stands. Every mode's runtime is published, including the flood modes most brands ignore.

Max output

400 lm

Runtime

2 h

Battery

Water rating

IPX4

What it gets right

• A 90 CRI flood, which matters more than lumens when you are diagnosing anything
• Spot and flood in one body with runtimes published for both
• Magnet, clip and a stand that lets it point where you need it

What it gets wrong

• Sealed lithium-polymer cell
• IPX4 — it handles a splash and not a puddle
• Four hundred lumens is modest if you want to light a whole garage

Published specification

• Spot high: 400 lumens, 141 m, 2 hours — Streamlight published specification

5. Best work light that publishes all four modes

Streamlight FlipMate

Lumens per dollar

6

Streamlight's answer to the COB panel is an LED panel with a 90-CRI mode, and a runtime printed beside all four outputs. You pay several times what a COB bar costs and you get a quarter of the lumens; what you get back is light you can judge color by and a 2-meter impact rating.

Max output

500 lm

Runtime

4 h

Battery

Sealed

Water rating

IPX4

What it gets right

• A runtime beside all four outputs, including both 90-CRI modes
• 90 CRI at 4,000K — the only work light here you can judge a color by
• A numbered 2-meter impact rating and a numbered IPX4 water rating
• Magnetic base, hang hook and a head that turns 270 degrees

What it gets wrong

• Five hundred lumens against two thousand from a COB panel costing a fraction as much
• IPX4 is splash resistance, not immersion
• Battery capacity and replaceability are not published
• No beam distance or candela figure for either emitter

Published specification

• Cool white, high: 500 lumens, 4 hours — Streamlight published specification
• Cool white, low: 250 lumens, 5.75 hours — Streamlight published specification
• 90 CRI (4,000K), high: 400 lumens, 4 hours — Streamlight published specification
• 90 CRI (4,000K), low: 200 lumens, 6 hours — Streamlight published specification
• Emitters: Cool white LEDs plus 4,000K 90-CRI Color-Rite LEDs — Streamlight published specification
• Water rating: IPX4 — Streamlight published specification

How we ranked these

Published output over live price, as everywhere on this site, with two adjustments stated here because they change the order. A light that publishes no numbered water rating is marked down, which costs the OMNI 2K — NEBO describes it as "water and impact-resistant" and publishes no IP figure, and a word you cannot check is not a specification. A light that publishes a CRI figure is marked up, because on a work light that number is the difference between seeing a fault and missing it.

Note what the ledger arithmetic does to this page honestly: the COB lights win it, by a lot. That is the real finding. COB is the correct answer when lumens per dollar is the question, and the two Streamlights are here to show what the extra money buys when it is not.

What to check on a COB spec sheet before you buy

COB listings are unusually noisy, partly because the format is cheap enough that unbranded sellers flood it. Four checks separate the ones worth buying.

1. 1.Is there a runtime beside every mode? NEBO publishes one for all six modes of the OMNI 2K and all seven of the SLYDE KING 4K. A listing that gives a lumen count and a battery capacity and leaves you to divide one by the other is telling you it has not measured anything.
2. 2.Is the water rating a number? 'Water-resistant' is a word. IPX4 and IPX7 are test results. The OMNI 2K has the word and not the number, and we mark it down for exactly that.
3. 3.Is there a CRI figure? Almost never on COB, which is itself the answer — but if color accuracy matters to your work, this is the first thing to look for and the quickest way to disqualify most of the category.
4. 4.How does it attach? A base magnet, a hook and a stand are three different capabilities and a light with one of them will be in your way at some point. Magnets are the most useful and the least specified: no manufacturer publishes a holding force.

There is a fifth check that is not on the spec sheet at all: how the panel is diffused. A bare COB array without a diffuser is a glare source you will end up turning away from, and the only way to assess it is to look at the product photograph for a frosted cover.

Why COB took over the cheap end

A decade ago a budget work light meant a halogen tube on a stand, a bank of discrete LEDs, or a fluorescent wand. COB displaced all three for a straightforward manufacturing reason: once you stop packaging each die, the cost per lumen collapses, and a format that produces a wide soft flood needs no optics at all. The emitting surface IS the fixture.

That is also why COB arrived at the bottom of the market rather than the top. The things it gives up — collimation, color fidelity, per-emitter binning — are precisely the things that matter in a premium light and are irrelevant in a twelve-dollar magnetic bar you stick under a hood. It is a genuinely good solution to the cheap-flood problem rather than a cut-down version of something better, and the honest conclusion of this page is that most people wanting to light a garage should buy one.

The brand pattern worth noticing

Three of the five lights here are NEBO and two are Streamlight, and that split is not an accident of selection. NEBO builds most of the COB lighting worth buying at this price and publishes a runtime beside every mode of it. Streamlight does not sell a COB work light at all in the range we cover; its answer to the same job is an LED panel with a 90-CRI mode, at four times the price per lumen.

That is a genuine strategic difference between two companies rather than a quality ranking, and it maps exactly onto the choice this page is about. If you want light, NEBO. If you want to see detail accurately, Streamlight. Our wider work-light ranking covers the rest of the category.

What we cannot tell you

We have not measured any of these lights. We cannot tell you the actual CRI of either NEBO panel, because NEBO does not publish one and we will not estimate it; we cannot tell you how either brand's output holds up over the published runtime, since neither publishes a sustained figure; and we cannot tell you how the OMNI 2K survives rain, because the only water claim attached to it is a word. Every figure above is the manufacturer's own.
