最新の会社ブログについて LED vs Halogen vs Fluorescent: The Only Machine Light Comparison You Need

Three technologies, one workbench. Here is what each one actually costs you in heat, power, light quality and replacement trips to the stores — with the answer most shops arrive at.

Every machine shop has a drawer of old halogen lamps and a story about a fluorescent tube that hummed until it gave up. Here is the honest comparison — not the marketing one.

1. Halogen: Cheap to Buy, Expensive to Run

Halogen is the old friend who never leaves. It is bright, warm and familiar — and it runs at 200–300 °C, turns half its power into heat, and dies in roughly 2,000 hours. On a machine that runs 5,000 hours a year, that's two or three replacements a year, plus the energy bill.

Power: 100–200W for a usable beam.
Life: ~2,000 hours. Measured in months, not years.
Heat: enough to warm your hands — and your part.
Color: warm yellow, hides fine defects.

2. Fluorescent: Even Light, Fragile Life

Fluorescent tubes spread light evenly and cost little per watt. But they are glass, they hum, they flicker as they age, and they contain mercury. In a machine shop, they are one dropped tool away from being a cleanup job.

Power: 20–60W, decent efficiency.
Life: ~8,000 hours, if nothing bumps it.
Weakness: vibration, cold, coolant, mercury.
Color: cool white, but CRI varies wildly.

3. LED: The One That Pays for Itself

An LED machine work light uses a fraction of the power, throws a directional beam you can actually aim, and runs for 50,000+ hours without changing a bulb. The upfront price is higher; the total cost is dramatically lower.

Power: 10–60W for a usable beam.
Life: 50,000+ hours — a decade of shifts.
Heat: almost none at the front; the driver handles the rest.
Color: choose 4000–5000K neutral for work, 6000K for inspection.

4. The Comparison Table, Without the Fine Print

Factor	LED	Halogen	Fluorescent
Power for similar light	10–60W	100–200W	20–60W
Typical life	50,000+ h	~2,000 h	~6,000 h
Beam control	Excellent (optics)	Poor (flood)	Poor (tube)
Heat output	Minimal	High	Low
Vibration / coolant	Tough (IP rated)	Fragile filament	Fragile tube
Upfront cost	Higher	Lowest	Low
Lifetime cost	Lowest	Highest	Medium

Three lamp heads compared on a workbench: halogen, fluorescent tube, LED — Same job, three lifetimes. The halogen glows warmest and dies first; the LED stays bright for a decade.

5. So Which One Should a Shop Buy?

For a machine work light, LED is the answer in every realistic case — except one: a shop that needs absolutely minimal upfront spend and replaces lights quarterly anyway. If you're that shop, halogen still works, but you're paying the tax somewhere else.

For every shop that runs two shifts or more, the math is not close:

LED pays for its higher price in energy within a year.
It pays for itself again the first time you don't stop to change a bulb mid-job.
And the beam control means it earns its keep on quality, not just on the meter.

"Halogen is cheap on the shelf and expensive on the meter. LED is the opposite — and the meter wins."

ONN · Machine Lighting

Made for machines, not for shelves

Every ONN LED work light is engineered for the workshop: cool output, real beam control and a driver that survives your spindle. If you're converting a machine from halogen, tell us your mounting — we'll match a light and arm for it.
