Thank you rightlydividing, that seems to be about 3x the price I just found at bulbs.com; but, it seems they claim to last twice as long, plus, apparently have some positives with full spectrum light and etc. Worth it in your opinion?
Since my stock of 100’s will carry me another year or more, I haven’t bought at either website. I tend to want the rough service bulb over a standard duty, but that is because of such variations in the quality of standard bulbs. My stockpile is Sylvania and I an not thrilled with their lifespan. Then there is this place:

but I an not impressed there either.
