F2 led headlight was launched on September 2017. it is a high performance led headlight with fan, the double beam led bulb are designed with 4 CR CSP led chips while single beam led bulb has 2 pcs of CR CSP LEDs. The maximum light output of F2 led bulb can reach 6000 lumens.
The F2 bulb is housing one PCB board in middle with opposing LEDs on two sides that decrease the distance between two side LEDs. With this special design, it can make the thickness of light source close to the tungsten filament of the halogen bulb.
The F2 headlight using a small size fan is easy to install which would not influence to mount the dust cover. The bulb of F2 used 6003 Aluminium alloy with a decent surface treatment that creates a good texture for the bulb. Its operating power can up to 36W which will have a better canbus performance than the common 25W led headlight.
Next, we test the F2 led headlight performance, the reviews are shown as below:
Testing the led bulb with 13.5 volt power supplied for 30 minutes and the room temperature is about 24-25 degrees, the led bulb surface temperature is as below:
The temperature of led bulb at the beginning | The temperature of led bulb after 30 minutes
The temperature of heat sink at the beginning | The temperature of heat sink after 30 minutes
The operating temperature of led chips keep at about 110 degrees, the junction temperature of CSP LED is 145 degrees, the operating temperature of this bulb is set in a reasonable range.
We test in 4 meters from the wall. And take the photo by SLR camera in setting ISO: 100, Shutter Speed: 10, Exposure: 10. Get the beam pattern image as below.

The brightness of F2 headlight would be out of your expectation if you are chasing for a higher brightness and a convenience installation, this series product without dark spot has a flat cut-off line and good light distribution is suitable for your replacement.
Standards for Headlight Beam Patterns -- edited by Kevin This article will discuss headlight beam patterns and the standards that agencies such as ECE/DOT require. The following points will be addressed to help gain a better understanding: 1. What does the original ECE front headlight testing graphic look like? 2. The original ECE front headlight testing graphic combine with driveway image 3. Some testing points that need to pay more attention to 4. Other standards used in other countries and areas (SAE/ADR) How do we define a safe and effective headlight beam pattern and what are the standards it has to meet? Most people would say they want a headlight that is super bright, covers a large area in front of the vehicle and has uniform illumination with no dark spots. But can this be achieved and still meet the standards set forth by ECE (E-mark) or SAE (DOT)? The short answer is, YES! The keys to optimal performance are to be sure the light is focu...
This is our new M2 LED Headlight series launched on November 2018. Its single beam housing with 2 pics CR CSP led chip while the dual beam housing with 4 pics leds, M2 led headlight kit can reach 6000 Lumen output. With an advanced dynamic design, high counterclockwise and low vibration of the fan, the M2 LED Headlight to work out the issue of noise in a safe situation. The bulb of M2 used 6003 Aluminum alloy, and bulb body is integrated by the hot-pressing process for better heat dissipation. And it is using double layer copper PCB which provides a good heat dissipation. Because of the high adhesion between the double layer copper PCB, it is beneficial to the heat dissipation and extends the lifespan of LEDs, the LED chips would not burn out easily. All in one style, the length of the bulb body is 77mm, the width of the heat sink is 31mm. The compact bulb body is close to the halogen bulb size LED Bulb Operating Temperature Testing Testing the led bulb with 1...

This is Blade led headlight which was launched on May 2018. Its double beam led bulb was designed with 24 pcs of SEOUL CSP-Y19 LED CHIPS, while the single beam led bulb was designed with 12 pcs of SEOUL CSP-Y19 LED CHIPS. Take the H11 led bulb single beam as an example, its length is 87.3mm, the width of its heat sink is 32mm. For the bulb body part, the length is 41.9mm and the width is 12.mm. Besides, the distance between opposing LEDs is 2.54mm, almost equivalent to the filament width of factory halogen bulb, which is 2mm. Generally, its volume is relatively compact compared to others fanless led headlights. The heat sink of Blade led headlight using 6003 Aluminum alloy, heat sink and bulb body are integrated by the hot pressing process for better heat dissipation, which can’t be disassembled. LED Bulb Operating Temperature Testing : Testing the led bulb with 13.5-volt power supplied for 30 minutes and the room temperature is about 25 d...
For the PCB boards now in application to LED headlight, there are mainly four kind of materials, Fiberglass(FR4) PCB, Aluminum PCB, Copper PCB and Ceramic PCB. It is a good deal to understand the distinctions for these four types PCB. Which PCB you choose depends on the circuit design construction of the headlight. FR4 vs. Aluminum PCB Price Comparison In the cost comparison, the Aluminum PCB is more expensive than FR4, as well as more superior in performance. Thermally conductivity Aluminum PCB has a great capability of thermal conductivity than FR4 which makes them play an important role in LED lighting technology. Technology practices The thermal conductivity dielectric material of Aluminum PCB is a thermal bridge that connects the components and metal plate. It can transfer heat to the heat sink through the core automatically. An Aluminum backed PCB is assembled with aluminum backing, highly thermally conductive dielectric layer and the standard circuit lay...

I think many people will meet this situation while shopping two similar products but with a great difference on prices.it is hard to make a choice for you, because you want to purchase the cheaper one but also worry about its quality as well. It is saying that you get what you pay. This is the best description of the current electronic products industry condition in China. Even high-value product like the laptop, or a cheap product like power bank or led light, we can find many similar products from different manufacturers. How can we identify which one is good and which one is in bad quality? We should take the product shell apart to see what kind of electronic component they used inside. In this way, we can understand the reasons why the suppliers always say that the price they offered is the best price and couldn’t be low, while another supplier can casually offer you a price cheaper 5USD, or 10USD. On our last post: How to Identify Genuine PHILIPS G7 or Fake PHILIPS G7 LED Headl...
Dear Our Esteem Clients, Recently we found that there is a counterfeit G7 PHILIPS LED headlight sold in the market. Whatever on appearance or packaging, they just totally copy our G7 LED headlight without any creation. We can not allow this happened and have requested our lawyer to suit this company. In order to avoid the situation that our esteem clients buy the fake products and cause any loss. We write this article to teach you how to identify a genuine G7 led headlight and the fake one. There are many detail difference between these two headlight bulbs: - Different Gloss - ACL mark - Craft and Detail - Cutting Curvature - Surface Craft - Thickness of Chuck - Solid metal and hollow metal on the connector - The width of the hanger - The surface craft of driver - LEDO G7 has scale mark - Counterfeit one has obviously cut burr - G7 Ledo use high hardness plug same to PHILIPS X-treme Ultinon led headlight - Different plug shape The craft details and electric component ar...
