The headlights don't seem to be that bright lately. I've been using them for more than two years, and (making excuses) I'm worried that they might burn out at any time.
LED development seems to have made a lot of progress, and even the new SMAX has been equipped with LED headlights as standard, so people are starting to be interested in using LED lights again.
After looking at it for a long time, I found it to be a dazzling array of products with so many styles and huge price differences. But according to past experience, "you get what you pay for" is correct.
After doing research for days, I fell in love with Philips Radium Light and De'an, and finally chose De'an with difficulty.

Content includes testing and brief introduction to installation
================================================== ====
1. Let’s first review the condition of my previous 85/80W halogen yellow light that is now out of print. We can find that the low light has been worn out due to frequent use.
Many people say that using a high-wattage light bulb reflector will cause fogging. I have used this one for four years (replaced it once, and used it for an average of two years) without fogging.
Ceramic lamp holders are used
2. Let me introduce my test environment, which is 4 meters away and illuminated on the wall.
Then use brightness measurement.
The measurement method will draw a circle with a single point and move it about 5cm, and take the highest value. The photo is 85/80w. At that time, the test still had 1250 LUX, but now the highest value is only 917 LUX.
3. Let’s change the introduction of today’s protagonist.
Dean 8th Generation XLED
4. That’s the package contents
5. The host is not large in size
6. There are only two connectors, one is connected to the original H4 power supply, and the other round connector is connected to the LED light.
7. LED lights
The biggest selling point of this product is probably its brightness and light type. Like the Radium Light, it uses a hood and double-sided light-emitting design.
The only difference is that De'an has a fan design
In addition, the motherboard part of De'an adopts copper design.
8. Installation
There is no heat sink design at the rear of this LED, so there is plenty of space just like the original one.

9. Currently, the mainstream LED light-emitting directions on the market include up, up and down, left and right, four sides, three sides, fish-eye design, etc. This one emits left and right light just like the Radium God.
10. Light type
Compared with the original halogen lamp, the tangent line is still there, but it is not as obviously slightly bent as the original one.
And the brightest position of the main beam is slightly lower. After installation, I personally adjusted the lamp to point upward.
Near headlight
far light
It's so bright that I forgot to measure it (I'll make up for it later when I have the opportunity). Because it's less likely to be used, I don't have time to measure it in detail. With this light type, the range of high-light illumination doesn't seem to be its strong point.
11. Actual measurement
The measurement method is to draw a circle of about 5cm with a single point and take the highest value. It really beats my 85/80w Osram.
12. Glare test
The front is at the same height as the lamp
Super surprising, less dazzling than the original one
If you look closer, you will find that although the light is emitted from the left and right, the main light reflection areas are at the top.
13. Front oblique 45 degree angle
Will look directly at the main body of the lamp, but the original factory will also do this
Besides, it's not too dazzling.
=========================================
in conclusion:
After the test, one thing is certain: the brightness of current LEDs is really not inferior to traditional halogen lamps. But it also needs to be matched with well-designed lamp bodies and lamps.
Ask me what the C/P value is?
To be honest, traditional halogen lamps may still have a price advantage. Although the brightness is not as good as this LED, the overall light pattern and brightness are above average.
(PS: 85/80W 8, non-original 60/55W)
