If you were looking for heat lamp bulbs than these would be a good choice. If you want actual light dont buy these.
These bulbs just put out a dim orange glow, about the same as a burning match.
I know its not because they are "vintage style" bulbs, i have 60 watt ones from a local store in other places and are much brighter.
Spend the extra $ to get good bulbs.
Brand new wont charge above 70%. Using oem yuneec charger
Put into drone take off, immediately drops to 16% with a low voltage warning.
Lasts about 3 mins total of flying time.
Both battery's do the same thing.
