Camp style LED Lamp

thingiverse

I've always been a fan of the camp lamps that resemble actual table lamps. These have fallen out of fashion in recent years due to their limited lifespan and the widespread adoption of LED lamp designs with a more utilitarian aesthetic. I decided to create an LED version of a table lamp-style camp lamp, one that's perfect for use in home power outages or outbuildings without electricity. These battery-powered lamps are ideal for situations where electricity is scarce, such as during extended blackouts or when working outdoors. Here's what you'll need: A 12v G4-base LED light, similar to those used in cabinet and landscape lighting. I opted for a cheap 12v LED light from Walmart, which claimed to be a 20W equivalent but actually produces only 2.5W of power. Any 12v G4-base LED light with a 20W equivalent rating will suffice. A G4 socket is also required. You can find a pack of 12 on Amazon, listed as "DiCUNO 12pcs Bi-Pin Base, G4, etc." The URL for this product is https://www.amazon.com/dp/B01N42T7R2/ref=cm_sw_r_tw_dp_U_x_GrEOEb1ZBXB4T. A DC rocker switch is another essential component. I used a switch with plastic spring insert tabs, which fit into a hole approximately 19.4mm X 12mm in size. If you prefer to use a different supplier, you can find a similar product on Amazon, listed as "MiMoo 20pcs On/Off Rocker Switch" at https://www.amazon.com/dp/B07B2S5QYN/ref=cm_sw_r_tw_dp_U_x_buEOEbKP199BM. Finally, choose your preferred 12v battery pack. I opted for an 8-AA alkaline or 10-AA NiMH configuration, using a standard 9v battery connector. NiMH batteries discharge power more steadily and last longer than alkaline AA batteries, but they don't hold their charge as well when stored. With a capacity of roughly 2500mAh per AA cell, you can expect your LED bulb to shine for around 12 hours from an AA battery pack, assuming the bulb is reasonably efficient.
