Hi everybody
just completed the upgrade from incandescent bulbs to LED for Solo and Cut (+ a few more switches) for my 4048 G+. These JKL LED seem to be the only replacement that do not need DIY modifications. The red LED are ok for Solo switches without any lamp filter. While the color is completely different from the originale amber, they recall the Duality red colored Cut switches so I think this solution may be accettable as the lack of genuinity is compensated by the reliability. The green LED are ok too without any lamp filter and are quite similar to the original green switches where fitted.The Solo lamp is more complicated as the LED alone is way too cold. I have tried a lot of lamp filters and I think these orange ones from JKL are giving the best result (specs on the pictures). The color in the picture is not 100% realistic...the LED Solo switch seems a little yellowish and less warm but it's rather due to the quality of my mobile camera.
Each JKL LED lamp costs 3 USD, the lamp filters cost 0,20 USD (minimum 100 pieces)
