Philips Hue disconnects

Hello, I have a Philips bridge and I bought an outdoor light for it. They are about 10 meters apart.
Unfortunately, the light bulb from the bridge keeps disconnecting and reconnecting. I don’t know why.
It doesn’t work anymore than it does.
I have about 30 devices of different brands on Homekit and none of them do it for me. Can you please advise me? Thank you very much.
