Courtesy of 4sevens is this 700 lumens Tiablo ACE.
What can I say, 700 lumens in a hand held LED flashlight?
It wasn't that long ago we thought that the Luxeon was bright at 30 lumens, and many of us still use the ArcAAA......
Size -
it's got a big head - but it is not enormous -
the body is for 2x CR123 and there is a supplied extension to make it a 4x CR123 light.
Head -
this is my standard scanned pic of the heads - but because the head is big and deep the LED emitters are out of focus.
Emitter in focus -
Close up of Tiablo ACE head (left) - A10 head (right)-
Emitter details ACE - Cree MC-E (left) - A10 R2 (right)
The Cree MC-E is a 4 die emitter.
The Tiablo ACE specs are not clear to what lumens ratings apply to what battery configuration - or if the 700 lumens applies to all battery configurations.
But I can tell you this sucker's BRIGHT!
2x CR123A -
vs. Tiablo A10 (R2) rated 260 lumens Max - both on 2x primary CR123
it's pretty obvious that the Tiablo ACE is noticably brighter - even in the full normal exposure. The -2 Stops underexposed shot will need some explanation (see later in the 4x CR123 configuration**)
vs. Fenix P3D- RB100 Turbo (rated 200 lumens) - both on primary CR123A -
what is a pretty bright pocketable flashlight - the Fenix P3D-RB100 (rated at 200 lumens) is dwarfed by this Tiablo ACE.
4x CR123 -
this configuration should be the brightest possible as the light is running on 12 Volts
vs. Tiablo A10 Max -
Afain it's very obvious that the ACE is noticably brighter than the A10.
The -2 Stops Underexposed shot might not be quite valid here or above**
because I managed to take this -2 Stops Underexposed shot literally less than a minute before -
because the shutter speed was very high (1/800 sec) due to the brightness of these lights -
it managed to miss the PWM light pulse -
resulting in showing the beam as black -
yes, the A10 even on Max is still pulsed/PWM - albeit a fast one -
I can easily see the pulsing on the LCD screen of my digicam, which made me double check the brightness setting.
So PWM makes humans see different levels of brightness by different duty cycles - and our eye/brain combination averages the light out.
But unless the camera catches a few pulses - it is not averaging -
case in point is my dark beamshot -
so I do not know how valid the -2 Stops Underexposed comparisons are for A10.
However the Fenix P3D-RB100 is constant current regulated -
This set looks similar to the comparison with the ACE on 2x CR123A
So from this qualitative/subjective comparison - I would guess that the 700 lumens rating applies to 2x or 4x CR123....
Like I said this sucker's BRIGHT!
Just to put things into context 700 lumens is somewhere between a 40 and 60 watt standard household light bulb - GE rates its 57 watt softwhite light bulb at 770 lumens and we know a 60 watt light bulb will light up a whole average sized room - imagine that light focussed ....
well, you don't have to - just try a Tiablo ACE

I wonder what the total cost would be for the light, two lithium batts and the required charger would be. How many power levels does this light have?
