Here is a tutorial for building a big lumen tube, with a diameter of 150mm, to measure the light output and the temperature of a torch.
This orange Skilhunt H150 is a AA sized headlamp with magnetic charging and it comes with a Nichia 519A 3000K emitter. It can be powered by either a AA Ni-MH cell or a 14500 Li-ion cell. It is available with a few different LEDs (CREE XP-L2, Nichia 519A) and different colours (orange, green, gray, black).
IMALENT reached out on BLF to ask if I would like to review anything. I asked for the IMALENT MS12 MINI because I thought that I would be capable of testing it using my 90mm DIY lumen tube. I was wrong.
The Acebeam E75 is a 21700 sized torch with four emitters, a strike bezel, built-in USB-C charging, battery level indicators, and an electronic side-switch. This particular version has Nichia 519A 5000K 90 CRI emitters. It is also available in cool white with a 6500K colour temperature.
The Mateminco MT-911 is a 26650 thrower with an XLD-G90 emitter, an Orange Peel reflector, and an electronic side switch.
The Acebeam Pokelit AA Ti is a forward-clicky AA sized torch with a what appears to be a blue topographical design. It has a high CRI Nichia 519A emitter and it can take Alkaline, Ni-MH or 14500 Li-ion cells.
NEXTORCH kindly provided the NEXTORCH TA30C MAX Tactical Torch for review. It has a CREE XHP50.3 HI emitter and it takes a 21700 cell. The large tail switch allows momentary modes to be accessed while a rotary switch can be used to permanently select a mode.
Olight Australia kindly sent the Olight baton 3 Pro Max for review. It is a 21700 EDC torch with a TIR optic and a floody emitter. This particular version has a Cool White emitter. There are also Neutral White and Warm White versions.
