Reviewers describe the Nitecore NU25 UL as a functional, lightweight headlamp that's a good match for backpacking and outdoor activities. They point to the waterproof build, the essential feature set, and a surprisingly low price. The 400-lumen output struck some as modest, but the consensus is that it performs solidly for ultralight users.

Nitecore UT27 MCT 800
2 sourcesall derived$54.95as of Oct 11

The Nitecore UT27 MCT is a light, rechargeable headlamp for outdoor use, with 800-lumen output and a Multi Color Temperature (MCT) LED system covering three color temperatures. Reviewers noted the IP66 rating and 1-meter impact resistance, which hold up to rugged treatment. Build quality on previous versions came up as a concern. Hikers, climbers, and campers who want a reliable, multi-function light are the audience, though its 14.5-hour capacity may fall short for anyone needing long runtime at maximum brightness.

Strengths
  • — Multi Color Temperature (MCT) system with three color temperatures (3000K, 4500K, 6500K) and varying CRI values
  • — IP66 rating for waterproof and dustproof performance with 1-meter impact resistance
  • — Rechargeable HLB1500 lithium-ion battery included with USB-C charging capability (full charge in 1 hour 45 minutes)
Watch-outs
  • — Limited battery life at maximum output (up to 14.5 hours with stable output)

How they stack up

Nitecore NU25 400 UL

Against the Silva Trail Runner Free H it is cheaper and lighter, but it gives up the Silva's hybrid battery system and its simpler brightness switching. Among ultralight rechargeable lamps its strength is feature count per gram rather than raw output.

Nitecore UT27 MCT 800

The Nitecore UT27 MCT 800 puts out 800 lumens, against 600 lumens for the Nitecore NU27 600 and 700 lumens for the Fenix HM50R v2. Like the NU27 600 it offers three color temperatures and an IP66 rating, short of the Fenix's IP68. At 74 g with battery it is heavier than the Knog Bandicoot 250 at 59.5g, which puts out 250 lumens.
