These Bulbs are of excellent quality for an excellent price. The 6500K, Daylight types are my favorites and they can be hard to find. I now have an excellent source with MCM.
I have purchased other electronic products from MCM and never been disappointed. The quality of the product purchased, the service and shipping charges are all excellent. Shipping has some times been free for Speakers I have purchased ---- and they were heavy.
MCM Electronics gave me terrific service and great prices. I will cheerfully shop with them again for my electronic needs.
