Strange - not sure what to suggest I'm afraid.
Do you have any Bluetooth sniffing devices you might be able to use to see if there's a difference in how Espruino writes to the Playbulb?
The only thing I can think is that the Playbulb maybe has the handles for the characteristic in a strange order, and that's confusing Puck.js?
