Gemlite Bulb?

[Sentrex]

Picked up this beautiful little gym for 10 bucks today 

Threw a Xmas bulb in it for now.... can someone please tell me the correct size bulb it needs?

Appears to be a confetti gemlite.

See below - I prefer to use 25W  with a dimmer switch so liquid does not get to hot or overheats.  If left on too long the glitter tends to curl.  try not to  operate for more than 6 hours at a time. You have a real beauty here.  it's so clear.  BIG TIME SCORE!

Model number:  Mystique (750), Continental (850), Capri, Mediterranean, Confetti (650)

Appreciate the replies and ordered the right bulbs last night. Can’t wait to see how the glitter flows with the correct bulb.

Truthfully I will likely polish it up and sell it on eBay. Really want a nice giant but woman says I can’t buy one until I sell enough lamps to buy.

I'll be looking out for  ebay listing/
