I am using my €3 red LED bulb very happily for Multigrade. I don't know where to get them in UK and the bazaar from which I bought mine has all the colours except red (I think I bought them all).

The appearance has soft edges, which is confusing, because it could be either optical or chemical. But if the streaks are absent when processed in a dip-and-dunk processor so it has to be chemical.
