Are F2 LED Headlights Worth buying? (Test & Review 2018)

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:   LED Bulb Operating...

How to Aim and Adjust an LED Headlight Bulb Light Beam?

Well, when we search on google about how to adjust headlight beam, the posts on the search result will teach you to adjust the position of headlights by adjusting the headlight alignment screws. But, this method is just to adjust the light beam position (up, down, left, right), but can’t adjust the light beam if it is the scatted. Normally when we remove the original reflector and install an HID kit with the projector, we need to do this, or when we change a new halogen bulb which different to the original one, we need to re-position the height of the light beam.   If we are replacing the headlight bulb to be LEDs, we don’t adjust the alignment screws but adjust the light beam by rotating the socket on the headlight bulb. LED and halogen bulbs both work with the reflector. But, the different reflector has a different inner structure. LED can’t emit lighting with a 360-degree angle like the halogen bulb. So, when we make it fit into different headlight reflector, we gotta adjust...

Blade Led Headlight Test Report

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...

Fiberglass PCB vs. Aluminum PCB vs. Copper base PCB vs. Ceramic PCB

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...
