These were low stock at my local DSE so I had to call and they only had 1 left in stock, so check the store stock in your post code online before heading down to pick one up as a lot have low or no stock left.
Varta Floating Lantern $6.99 (comes with Varta 6V zinc carbon battery)
Also they have a clearance on 6v GP alkaline batteries so I picked up 3 as well.
GP 6V Alkaline - $1.99
Alternatively they also have zinc chloride batteries for even cheaper.
GP 6V Zinc Chloride - $0.79
These are about 1/3rd of the price of a Dolphin and come with a free battery, the tint is awesome as is the case with most incan bulbs but I find the beam pattern pretty ugly when shining it on the wall indoors (its still light here).
I don’t know what I’m going to do with it but I’m sure it will come on handy for something.
