LH351D 90CRI Spectrum Tests

shaved LH351D.

Modded Tool AAA:
CCT = 4490K (Duv –0.0031)

Color Rendering Index (Ra) = 94.2 [ R9 = 69.5 ]


I like this TIR LH351d light,

it has earned a spot on my mouse pad,
The tint is good during the day

and being twice as bright as my sw45k, cant be bad

respect the 351

of note
all the other lights in my edc rotation are 219b
this 351 is the only outsider to make the cut
I particularly like the pebbled tir beam, very even, useful at close range

efficiency test
with a depleted Eneloop AAA at 1.2v in the Tool that contactcr built w LH351s I got 55 lumens on max.

The same battery in my copper tool, powering an sw45k, gave me 25 lumens…

so yes, the LH351d Is indeed twice as bright as the sw45k… wow…
