LED vs Incandescent Flashlights - Pros and Cons
When it comes to flashlights, the classic incandescent bulb has mostly been superseded by LED technology. But each type of flashlight still has advantages and drawbacks.
Brightness
Incandescents produce light by heating a tungsten filament, while LEDs generate light via electrons moving through a semiconductor. This gives LEDs an edge:
- LEDs emit more lumens per watt, giving higher maximum brightness.
- LEDs maintain consistent output as batteries drain. Incandescent output declines steadily.
- LEDs focus light into a tighter beam, while incandescents spread across a wider angle.
For example, a 300 lumen LED flashlight will appear brighter than a 300 lumen incandescent thanks to its focused beam.
Runtime
No contest here - LEDs are far more energy efficient:
- LEDs convert over 50% of energy into light, incandescents just 10-15%.
- This gives LEDs up to 10x or more runtime from the same batteries.
- Runtime for an LED flashlight can be dozens of hours, compared to just several for an incandescent.
With their minimal power demands, LED flashlights will run for days rather than just hours of continuous use.
Durability
LED emitters are solid state with no fragile filaments. This gives them an advantage in shock and vibration resistance.
- LEDs withstand drops and impacts that would break an incandescent bulb's glass envelope and filament.
- Vibration from activities like motorcycling also takes a heavier toll on incandescent bulbs.
So for duty flashlight use, LEDs hold up better to inevitable drops and hard knocks in the field.
The Verdict
For most uses today, LED outperforms incandescent. Only nostalgia keeps incandescent on the market. But for some specialty uses like signaling or preserving night vision, incandescent remains an option. Either way - carry a reliable flashlight and don't get caught in the dark!
Choosing the Right Flashlight Batteries
Your flashlight is only as good as the batteries powering it. Choosing the right type and quality of batteries for your flashlight's needs is key to ensuring optimal performance. Here are the key factors to consider:

Battery Life
Runtime is critical - a flashlight does you no good with dead batteries! Battery life is affected by:
- Capacity - Measured in mAh. Higher capacity means longer runtime.
- Temperature - Cold weather saps battery life. Lithium batteries handle temperature extremes better than alkaline.
- Shelf Life - Alkaline batteries lose power even when unused. Lithium batteries retain charge for 10+ years.
For extended runtimes, choose high-capacity lithium batteries rather than lower-capacity alkaline cells.
Cost
Disposable vs rechargeable batteries have different costs:
- Disposable - Alkaline offer the best value, lithium cost 3-4x more but last 4x longer.
- Rechargeables - NiMH cost more initially but pay for themselves after a few recharge cycles. Lower operating costs.
Frequent use favors rechargeables, while sporadic use leans towards disposables.
Rechargeability
For flashlights supporting rechargeables, options include:
- NiMH - Inexpensive, lower capacity. Must be removed from light for charging.
- Li-ion - Higher cost, higher capacity. Can charge via USB while in flashlight.
Li-ion offers convenience, but has higher upfront cost. NiMH work well for removable batteries.

Fit
Ensure proper battery fit - mismatched batteries can damage your light. Compare battery specifications to flashlight's requirements for:
- Battery type - alkaline, lithium, NiMH, etc.
- Battery size - AAA, AA, C, D, CR123A, etc.
- Voltage - 3V, 4.5V, etc.
- Protected vs unprotected (for Li-ion).
With the right batteries installed, your flashlight will deliver optimal, reliable performance.
Understanding Flashlight Beams - Distance and Type
A flashlight's beam distance and type are key factors influencing its real-world performance. Selecting a light with optimal beams for your use case ensures it provides the illumination you need.
Beam Distance
This specifies how far the beam will shine while maintaining usable brightness.
- Shorter distance beams under 100m suit close-range use indoors or near the body.
- Medium distance beams of 100-200m work well for general outdoor use.
- Long 200m+ beams allow scanning large areas at a distance.
For example, a 100m beam flashlight is great for camping, while a 300m search and rescue light can spot objects much farther away.
Beam Types
Beam profile affects the spread and focus of light.
- Flood - Broad, diffused beam lights up a wide area useful for close-range task lighting.
- Spot - Long and focused like a laser pointer. Intense center spot picks out distant objects.
- Adjustable - Continuously focus beam from flood to spot.
Flood beams prevent tunnel vision but lack distance. Spot beams see faraway but only illuminate a small area.
Real World Examples
- An electrician working in a crawlspace needs a wide flood beam to see all around a close area.
- A boater scanning for buoys uses a narrow spot beam to cut through fog over long distance.
- A spelunker uses an adjustable beam, flooding caves for navigation and spotting formations.
Maximizing Performance
Consider your lighting needs, then choose an optimal beam distance and type:
- Flood beam for close-range area illumination.
- Spot for identifying distant objects.
- Adjustable for versatility between flood and spot modes.
- 100m+ beam distance for seeing farther.
With the right beam profile, your flashlight becomes a high-performance lighting tool for any situation.
