I’m using a shoebox with a lux meter.
Every time I measure the light it has been accurate to other’ trusted readings and my pwn, unless I have done something wrong this time.
When I’ll measure the current, I’ll update the post and remeasure the light output.
It is kind of strange they would overrate it by this much though.
At 2.3A, the XPL V6 gets about 1000 lumens. So even subtracting 15% losses from the lens and reflector, it should be doing 850 lumens, not 700 lumens.
They must also not be saying the truth about using an XPL V6, but a lower bin perhaps.
I’ll measure the current draw, and replace the light 3800k XPL with a 4000k 90CRI LH351D. If this gets more output than your 700lm CW XPL U18, then this will mean that they are using a lower binned LED than advertised.
