Fitted a red LED light over the chart table in the spring but when used a couple of weeks ago found it was more than useless as I couldn't see the majenta lines or marks at all. As we were crossing the new Sunk precautionary areas at night it was bit disconcerting but ok after I'd switched on the original white fluorescent lamp which I had left in position. What is the forums opinion on the best lamp to use? I was using the Imray C30 chart at he time.
