Review on Pack Tubular Light Candelabra Clear by Greg Roberts

I bought two packs of 6 to use in a lamp that requires 7 bulbs. The first bulb burned out within an hour! Several others burned out over the next few hours and days through.I've burned out 6 bulbs for a week now 3 are still on and I'll put in the last 3. I don't know if the bulbs are badly made or shipped in an envelope not a box is to blame , maybe it's a combination of both. Just know I won't buy them again. Also, the shipping box they came in was just a paper envelope. None of the bulbs were broken, but the severe wobbling in shipping must be for the longevity of lightbulbs have worked wonders.
