I was concerned about mounting the bulbs for one of our Christmas decorations (a red bird with a colorful "worm" garland - don't ask!) burning out each bulb, but didn't want to dump them. For the last actin I used these bare bulbs (no holders). It was a simple if tedious exercise to pull out the original bulbs, then pull the bulb out of its holder and thread the new bulb's wires back through the holes. Kind of a pointless exercise when you need to clear your head :-) Every one of the 100 lightbulbs I've replaced this way has worked perfectly! I would definitely go this route again as I only had to dispose of the original glass bottles and not a single plastic holder ended up in the trash.
