Another update, I have been looking for a new rechargeable light & I did pick up an Eveready light from K-mart that took 4 "D" batteries but I still wanted a rechargeable, but I could not afford the $50+ that most of the good units are.
I saw that Supa Cheap Auto had a lamp for $24 which normally was $39, I went & had a look & found it looked identical to the Bunnings one I bought except for the globe which looked the same as home energy savers with the twist in them, it also was identical to the one I saw in BCF, when I was hunting for a tube for my Bunnings one & BCF did not have any bulbs to show me for their one either!
I popped open the packet of the lamp in Supa Cheap & unscrewed the top & pulled out the tube AH HUH! same pin configuration as the Bunnings one & you can not get a tube with 4 pins in a square pattern anywhere in Australia!!!
So moral is, DO NOT buy a cheap lamp unless you know 100% you can get a replacement tube, I suspect BCF sells the same lamp! they also sell a lamp which has LED's instead of a tube, so this would be a safer bet.
As I was leaving Supa Cheap, I saw yet another rechargeable lamp for $15, I opened it up & found it had the standard tube with 4 in line pins which you can buy anywhere, I picked it up & when they scanned it I was only charged $10, bargain
