Review of Blue C9 Bulbs. Need more blue and not to fade.

This last box of 25 ea. C9 transparent bulbs is barely fair. They are not colored blue as much as they should be. They start off appearing as a light blue and seem to gradually fade to a light blue green. But these are better than the ones I last purchased from the same manufacturer a couple years ago which were much worse in the same regard. May as well have bought white lights. The only truly decent blue transparent bulbs I have found have been in the local hardware store appear to be made by a different manufacturer but they are in multicolor bulb packs of 10 bulbs or so, so I would have to buy 5 times the amount of bulbs I need to get a sufficient number of good blue bulbs for my application. Sad that I can't find a true good quality real blue bulbs in bulk anymore.
