Replace input port electronics board

Follow the guide below:


Required tools

  • Screwdriver - Torx 5

  • Screwdriver - Torx 6

  • Knife

  • Electronics board (PCB)


Step 1

Unscrew lamp casing

Using a Torx 6 screwdriver, carefully remove the 3 screws at the bottom of the case.

Screws are small and light, so make sure to place them in a safe spot to avoid losing them.


Step 2

Open the plastic casing

Carefully separate the two parts of the plastic casing. Make sure not to pull too fast as there is a battery cable still keeping the two parts together.


Step 3

Pull battery out from bottom casing

Gently pull out the battery.

If the battery is locked very tight, pull firmly but with care not to damage the cables.

Avoid using sharp tools such as pliers, which may damage or break the cables to the battery. This is a safety hazard!

DO NOT use sharp edge tools to pull battery out.


Step 4

Disconnect battery from electronics board

Depending on the version of you lamp, the battery will be attached to the electronics board in one of two ways:

Type 1)

The battery connector has 2 halves, 1 soldered to the board, and 1 attached to the battery cables. Using your fingers, gently pull the battery connector half. (Pulling the entire connector, might lead to breaking the solder.

You might find silicon glue around the connector; this is not hard to remove by simply pulling the connector away.

Type 2)

The battery cables are soldered directly to the electronics board (PCB). In this case you will need to use a soldering iron to melt the connection and be able to pull the cables out. Alternatively, you may clip the cables, one at a time.


Step 5

Unscrew electronics board.

Using a Torx screwdriver, remove the 2 screws from the board. One or both might be hidden behind the black foam piece.

Screws are small and light, so make sure to place them in a safe spot to avoid losing them.


Step 6

Lift up electronics board

Using a knife or a flat head screwdriver, carefully pry up the electronics board, once you are able to see the edges of the board you can use your fingers to lift and rotate it to expose the underside.

Be careful not to pull too far/hard as the board is soldered to 2 more wires underneath.


Step 7

Remove damaged PCB

This step requires specialized equipment for soldering, as well as important safety considerations:


Before starting to solder, make sure to wear protective eyewear, and after soldering, make sure to wash your hands thoroughly to remove any remaining chemicals.

Using a soldering iron, heat the two soldered contact points as shown below. When the solder turns into a liquid form, lightly pull the electronics board so that the cable being held behind is released. Repeat the step for both cables to fully release the PCB.



Step 8

Dispose old PCB as eWaste.

There is valuable material and minerals in the PCB you have removed. In order for it to have chances of being recycled, it needs to be disposed as eWaste, and you will need to hand it to a recycler.


Step 9

Place in new PCB

Install new PCB into plastic casing, while doing it, align and insert the red cable with the hole marked as (+) in the PCB. Do the same for the black cable into the hole marked as (-).



Step 10

Solder new PCB

With a soldering iron, heat up the area and the cable on one of the contact points, after a few seconds, bring the soldering tin close and melt a small amount enough to cover the exposed cable. Remove the iron and after a few seconds the solder will have hardened. Repeat this step on the second contact.

The right amount of soldering tin looks similar to this image.



Step 11

Reassemble the lamp

Following the steps 5-1 in reverse order, reassemble the lamp.
