You can t use ordinary LED white headlamps when you re traveling at night, you need yellow lights

I can use a normal LED white headlamp and save electricity more.

LED is the abbreviation of English Light Emitting Diode (light-emitting diode), its basic structure is an electroluminescent semiconductor material chip, cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and then sealed with epoxy resin around to protect the internal core, and finally install the shell, so the LED lamp has good seismic performance. The application field involves the production of daily household appliances and machinery such as mobile phones, desk lamps, and home appliances.

LEDs have high brightness but low illumination!

The light of the LED has a color difference in the eyes of people (in total darkness, use it to look at something red).

LEDs are cold light.

The yellow kind is close to daylight, does not produce chromatic aberration, and is a warm light source.

The color ratio of LED white headlamps is relatively poor, which is easy to make people deviate from the height of the object, and it is dangerous, while the reduction ability of yellow is relatively strong, so it is relatively safe.

Who said, I use LED-Lenser headlights, made in Germany, with a beam distance of 60 meters, the power is watts, very bright, I can see very clearly, and ordinary alkaline batteries are no problem for hours in a row.

It's just more than 200 yuan, which is much more affordable than PETZL.

There will be a white headlamp! Unseen!

Another reason is that the yellow light is bright.

As YK5 and FS Pirate Piggy said.

Cold light is more dangerous than warm light.

The illumination distance of ordinary LED is about 15 meters.

OK?

A flashlight with white light is better, and at night when the light is insufficient, the white light can be seen more clearly.

The white light is brighter, while the yellow light is softer and not as bright.

If you catch a bird in the wild, you will not be able to see it if you shine white light directly on its eyes, so you should use yellow light.

However, the main thing to catch fish is to be bright to see clearly, with cold white light can be a good distinction of fish, will not be like the low color of the ground warm white or yellow light will color the soil and fish at the same time.

Note: Because the habitat of each type of seafood is different, the best place to catch the sea is to choose a place with more shell sand.

There are stones on the seashore near the mountains, and these stones give birth to oysters.

The shell of this oyster is very sharp, and where there is no mountain, there is a stone dam, and there are oysters growing on this stone dam;

If there is slight contact with **, it will be scratched by the oyster shell. So it's best to wear military galoshes and gloves.

According to what I've learned, it's better to use a white headlamp at night. Here's a comparison:

1.At night, when there is less light, white light can help to see more clearly, while yellow light is comparatively softer and not as bright as white light.

2.In the process of catching the sea, the main thing needed is bright light to clearly distinguish the fish from the surrounding environment. White light can provide better contrast, making the fish easier to see.

3.Using a white headlamp avoids shining light on the bird's eyes, as direct exposure may make it invisible.

To sum up, it may be more appropriate to use a white headlamp for the sea at night. However, the choice of which color headlamp to choose also needs to be decided according to the specific use scenario and individual needs.

The yellow light has strong penetration, and it is used with EmminiNT HR20.

Generally speaking, the color temperature of street lamps is white at about 5000K, and yellow light at about 3000K.

Or warm white light. Yellow light or warm white light of about 3000K is more suitable for road lighting, because the light at this color temperature is warmer, the signal received by the human eye is softer, and the driving is safer.

The street lamp of about 5000k feels very cold and dazzling, which will lead to visual fatigue and affect the user's travel safety after a long time.

Different wavelengths give the human eye different color sensations, ranging from red, orange, yellow, green, blue, indigo (blue-violet), violet. The sensitivity of the eye varies strongly with changes in wavelength. For example, under good lighting conditions, the eye is 20 times more sensitive to light at a wavelength of 550 nm (yellow) than red or blue light.

This is also an important reason why most cars use yellow light in their fog lights and street lights on the road. Color temperature is a measure of the temperature of a color, not the brightness of a lamp. The color temperature of halogen lamps can range from 2300K to 7000K; The color temperature of HID lamps ranges from 4200K to more than 8000K; The higher the color temperature of the lamp, the less penetrating it is to fog and rain (the less bright).

Here's how different color temperatures behave:

Light color temperature light effect.

3000k yellow light, strong penetration.

4200K white with yellow, the original car is equipped with xenon lamp.

5000K light is completely white, the highest color temperature in Europe.

6000k light is completely white with a hint of blue.

Daytime under 6500k sun.

7000-8000k white with obvious blue.

Blue light above 8000K, with extremely poor penetration.

Recommendation: The color temperature of about 6000K is exactly the color temperature at which the whitest and slightly begin to turn blue, which is easy for the human eye to accept, not easy to fatigue, and improves safety, while halogen lamps are poor.

Yellow wavelengths are longer, less easily scattered, and diffraction is susceptible to irradiation, allowing it to be irradiated farther.
