This 5V LED lamp module offers a really bright light, which is compact and easy to mount. The unit is supplied with 9 white super flux LEDs, which collectively output around 16,000 mCd.

The unit incorporates current limit resistors, allowing it to be run from a 5V supply or 3 x AA batteries can be used (3 new batteries will last for around 5 hours).

The module makes a nice desk lamp when powered from our micro USB power supply (used to charge many phones, tablets and e-readers) which can be done by using our micro USB break out board.

Here is a video we have put together demonstrating the kit:

Question:

Is it possible to power the desk lamp kit using solar power i.e. through a charged super capacitor?

Answers:

  • Posted by Michael Lockhart on Monday, 21 November 2016

    Hi Martin, The desk lamp kit take a power source ranging from 2.5V - 5.5V and at 5V’s it will draw 175mA. It would be difficult to use a super capacitor kit which has been charged by a solar cell. The kit draws a fairly high current, and a super capacitor won’t provide a steady voltage. It is difficult to provide an estimation of how well this would work as I don’t know what capacitor or solar cell you are using. You would likely be better with solar cells and rechargeable batteries.

Question:

Hi, do the LEDs produce much heat? I plan on using them within an enclosed PVC case.

Answers:

  • Posted by Michael Lockhart on Friday, 20 May 2016

    The LED’s used on these kits don’t generate any more heat than a standard Led, as such they would be fine in a PVC case.

Question:

Hi, Is it possible to include an LDR in this circuit so that the light comes on as it gets dark?

Answers:

  • Posted by Michael Lockhart on Tuesday, 17 May 2016

    Yes it you would be able to use an LDR to trigger the circuit, the easiest way to do this would be to use the light activation circuit and connect the 5V desk lamp kit to the output on the board https://www.kitronik.co.uk/2112-light-activated-switch.html

Question:

Can this be soldered directly to the USB power lead (product code 4101) to make a USB desk lamp?

Answers:

  • Posted by Michael Lockhart on Monday, 7 September 2015

    A USB port outputs 5V’s, so yes you could connect the USB lead to this desk lamp kit.
