Replace bulb

hi, our spa light was dim so I watched a video that made it look relatively easy to replace the bulb. When we took the screws out and pulled the light out, it looks like there’s not a place to screw a light- like we might have to replace the entire fixture. I hope not since this is expensive! The model I see is luminair Hayward SPO533SLED100. 120v 25 watt. Is there a replacement?

Unfortunately, there isn’t a replacement bulb for that fixture. You’d have to install a complete light.
