Upgraded the multi emitter portion of old Black and Decker light with 4000k. No before shot but it was typical cold white and beam was narrow than I liked. The new emitters are much floodier.
Below it is a reading lamp with a cold white emitter that needed a 2300k swapped in its place. The 2300k is taller than the original so I had to crack the ice to make it fit.
Ever since I saw Djozz QX5252 clock mod I could not stop myself from upgrading from clocks around the house. Also made a bunch of fairy lights using this circuit with almost dead batteries. This one has been on 24/7 since November. (It’s perfectly visible in the dark but phone camera could not capture it without help )
