Yes it is a giesseman bulb! And If they do have it that would be awesome!
I agree. the midday are probably better.Seems no one has them. In the States any way.
One member here tried to order them from Germany and wnet thru PayPal.
He never got them and ended up getting his $$$ back.
Dang is right. They should be used together but the Midday is such a good bulb that it may not matter much.
