Trumpy,
I've had great experiences with the Sho-Me lanterns from Able 2 Products.
http://www.able2products.com/Pages/09.2770.htm We have used them at work, in an industrial environment, for over 10 years and they have proven themselves to be durable, reliable, and effective. I was impressed enough to buy one for my own personal use. One of the best things is that they look so ordinary that people don't 'borrow' them as much
Their specs aren't as impressive (when compared to other lights) as I thought they would be but I believe they would do a good job for what you described along with being lighter and less expensive than some of the others.
