Modified Little lantern

Firstly, thank you for a fantastic design. I have re designed the base and added a led holder for a couple of "T10 501 W5W interior WHITE Side light LED 11 WATT HIGH POWER CREE LED" from ebay. I also added two 3mm white led's.
So I now have 3 modes of light, night light with two 3mm leds, and med/ high brightness with either one or two of the 11 watt led's.
All powered by a 12v cable. This is to hang in our tent for our camping holiday later on in the year.
There is some room to add perhap
