I did say that I have compared new wilkos ones.
Mine is white, not bluey-white, production runs seem to change the spec from time to time.
Im still not going to get all gooey about a slightly brighter output from what I use as a back up. A lithium will be brighter than a Nihm battery as voltage is that bit more constant, but the same is true with a new alkaline battery, rechargables tending to kick out a slightly lower voltage.
