Amazon.com: 4Sevens/Foursevens Mini AA/ MA Black Finish / Cool White LED; 1XAA; 90 Lumens: Camera & Photo
it has strobe, low mid and high. some other models allow you to program out the strobe. no clip but you might be able to improvise. i have one and i really like it.
4sevens offers many other models. some have tail caps, this one dose not. recommending this one because it is simple and i actually own one.
