Absolute ripper deal for Pure copper Astrolux A01 BLF Edition (BLF Edition is just branding for BLF forum). Previous low was $10.61 for just the aluminium version as posted here - https://www.ozbargain.com.au/node/296181
These lights are great as keychain lights and works well when paired with eneloop pro's or IKEA Ladda AAA's. Also this one has the Nichia 219B emitter with over 90 CRI for outstanding color representation. Way better than those nasty cool white emitters on cheap lights. These lights never came below $19 USD with coupons and no other AAA copper flashlights available for this cheap due to high production cost and machining.

Copper flashlights develop unique character overtime due to patina and feels great in the hand.
Aluminium version is also available for USD3.97 (Code - 1ef9bb) with CPFItalia branding here - https://www.banggood.com/CPFItalia-Forum-5-ANNI-Nichia-219B-… but copper version is the true winner here. Both lights have same specs apart from Aluminium being lighter.
