I did buy a "UFO" from BCF for about $10 - I think it was on special. Something like
this.
The one I bought even had a keyfob remote control! I bought it here in Perth, tested it - fantastic! Different modes/brightness, and hangs from the top of the tent.
I then took it to Middleton for the rally. Black bike + 43 degrees + plastic light.... melted so bad the batteries wouldn't stay in.
Into the bin it went.
So, I'd recommend one of these as long as you don't put it in the oven.
