June Electronics Adds B-KING A3 Car LED Headlight Bulb with IP67 Sealing and Fan Cooling

June Electronics Adds the B-KING A3 Car LED Headlight Bulb to Its Automotive Lighting Range

Shenzhen, China — Shenzhen June Electronics Co., Ltd. has added the B-KING A3 car LED headlight bulb to its automotive lighting range. The A3 is a plug-and-play replacement bulb built around COB LED chips, an aluminium integrated heatsink with two copper heat pipes and a turbo fan, and an IP67 sealing rating. The company positions it as a practical halogen replacement for passenger cars and light trucks rather than a performance accessory, and publishes its specifications in full on the product page.

What the A3 actually is

The A3 is a two-pin LED bulb designed to fit the headlight housings of most common car models and trucks. It uses COB (chip-on-board) LED chips, a construction that places several small dies on one substrate and produces a broad, even light surface. Manufacturer figures for the bulb are listed below.

Thermal design is the main engineering focus

Most LED headlight failures in the field are heat failures, not chip failures. The A3 addresses this with three stacked measures: an aluminium heatsink that is integrated into the bulb body, two copper heat pipes that move heat away from the LED dies, and a turbo fan that pushes air through the assembly. The copper tubes matter because they transfer heat far faster than solid aluminium alone, and the fan keeps the heatsink working when the vehicle is stationary in traffic, which is when housing temperatures climb highest.

June Electronics rates the bulb for operation between -40 °C and 105 °C. That range covers cold starts in northern winters as well as the inside of a sealed headlight housing on a hot day, but buyers should still confirm that the housing itself has enough clearance for the fan end of the bulb.

Water and dust protection

The A3 carries an IP67 rating, which means it is dust tight and can withstand temporary immersion in water under defined test conditions. In practice this covers rain, spray, snow and washing, including pressure washing at a reasonable distance. It is a sealing rating, not a guarantee against a cracked lens, a damaged connector or a flooded housing, so installation quality still matters.

Lifetime and warranty: read the numbers carefully

The published operating life is more than 30,000 hours, with a total lifetime figure above 50,000 hours. These are manufacturer ratings measured under controlled conditions, and real service life depends on housing ventilation, ambient temperature and duty cycle. June Electronics backs the bulb with a two-year warranty, which is the figure buyers should use when comparing suppliers on commercial terms.

The A3 is available now. Standard commercial terms are:

• Minimum order quantity: 100 sets
