Those other lights are nice for what they are but I agree with MascaratumB. Hard to beat the D4 for the money. With a 18350 tube it becomes a truly miniature power house. Exceptional quality and great after sale support from Hank at Intl-Outdoor or Richard from Mountain Electronics. You can save a few dollars from Hank and wait for overseas shipping or order from Mountain for a few bucks more and get it quicker. You really can’t lose either way.
