Stop Guessing: How Much Brightness Do You Really Need for Your LED Headlights? (Lumens, Watts & Kelvin Explained)

Are you sick of driving in dim light? An LED headlight upgrade is one of the best improvements you'll make to your visibility and safety at night. When shopping for your LED lights, it's crucial to understand the technical information -- lumens, watts and Kelvin. What does it all mean? And what numbers are actually important for the road ahead? 

No more guessing. We at Q po Glo have put together a guide to help you understand the basics. We'll even explain how to choose the best LED lights to maximize your own visibility while staying compliant with the law.

What are Lumens? The Measurement of Headlight Brightness

Lumens (lm) is the key measurement to pay attention to. It indicates the total amount of visible light emitted from the light source. To put it simply, almost-all things equal, the higher the Lumens, the brighter the light. 

Difference between halogen and LED: For incandescent light bulbs, higher wattage resulted in brighter lights and more heat. In contrast, LED lights are very efficient. For example, a low-wattage LED light produces considerably more lumens than a high-wattage incandescent (some level of comparability exists between watts in halogen and LED lights).

Q po glo recommends - optimal lumen range: For a bright, safe, and effective upgrade to LED headlights, you should consider looking for an optimal lumen range that strikes a balance between increased visibility and decreased glare for oncoming traffic.

Headlight Type	Typical Lumen Output (Per Bulb)
Halogen (Stock)	700 - 1,200 lm
LED (High Performance)	3,000 - 6,000 lm

Q po glo's high-performance LED lights are designed to maximize the visible light that is shown on the road surface; glare doesn't impact the high-level of brightness provided by the LED lights. Being able to see more light on the road surface at night provides clarity, allowing you to react more quickly.

What is Kelvin? The Measurement of Light Color

While Lumens measure the brightness of your light, Kelvin (K) describes the color temperature. Color temperature matters for how the light looks, and how well your eyes perceive contrast.

• Low Kelvin (around 3000K): Emits a warm yellow-white light, like that of halogen bulbs. This is often preferred in fog and heavy rain, as the warmer light scatters less in those conditions.

• High Kelvin (5000K - 6500K): Emits a cool pure white, or bluish-white light. This light simulates natural daylight, which is optimal for alertness and your ability to see contrast at night.

Q po glo Recommends: Color for Visibility

• For the best ability to see and observe details while driving, the majority of drivers want a color temperature that closely mimics natural daylight to match their outdoor vision of color as closely as possible and to have a greater aesthetic enjoyment in their driving

• Best Driving Color: 5000K - 6000K (Pure to Cool White). This range has a crisp bright appearance, and when used for motor vehicles can illuminate the roadway well.

• The All-Weather Option: Q po glo also offers innovative multi-color LED headlights (such as our Tri-Color series), which allow you to select a yellow color light (around 3000K) that will penetrate better in fog, heavy rain, or snow.

What is Watts? The Measure of Energy Consumption

• Watts (W) represents the power used by the bulb. For LED headlights, this refers to energy efficiency, not brightness.

• Lower Watts, Higher Lumens: This is the beauty of LEDs. A Q po glo LED headlight can use "less" power (lower watts) than an old halogen bulb, and produce many more Lumens of light output (brightness). This means less strain on your car's electrical system, and less heat being generated on the bulb itself.

• Watch for Ridiculously High Watts: Some brands indicate exaggerated Watts, as a gimmick to show they are able to produce more output than the competition. Always look for the Lumens, that's the telling number about how bright the light will actually be on the road.

Q po glo Takeaway for your next upgrade

Keep these 3 simple rules when selecting your next LED headlights:

1. Look for Lumens first: 3,000 to 6,000 Lumens per bulb is a huge, road-safe improvement for visibility.

2. Pick a Color: 5000K to 6000K will provide pure white, daylight-like brightness while driving.

3. Consider the Brand: The Q po glo brand is a great place to start as you'll be guaranteed a proper beam pattern, premium quality cooling (which keeps the brightness long term), and legal compliance.

Upgrade for a higher level of nighttime safety and a premium look for your vehicle with the right LED headlights. See the road like you've never seen before!
