I snagged one at Home Depot today. They were in an isle stand next to the padlocks. A quick check showed over 530 lumens when first switched on. After a couple of minutes of futzing it was at 483 lumens. So, Defiant looks to be a heck of a lot more honest than Coast (Coast G20 for $3 at Home Depot). I’ll try and do a full test run tonight.
