DQG Tiny AAA 7 (Cool white) measurements

The DQG Tiny AAA is one of the smallest (12,8 × 59,3 mm) flashlights to use an AAA or 10440 sized battery. It weighs 13 grams without a battery, 22 g with a 10440. I tested the latest (as of 1/2016), 7th iteration of it. It comes bare without any accessories in a plastic bag. Battery has to be purchased separately.

Switch is a twisty type. Changing between the two modes is done by switching the light off and back on again. Threads on the head feel smooth enough, but the first couple of turns are a bit finicky. You can also screw open the tailcap, but because of its small size and sharp machined edges the head is preferred when changing the battery. There’s a magnet in the tailcap.

The light is available with two emitters. I measured the cool white version with a Cree XP-G2 LED. It was specified as 6000-6500 K but measured a bit below this (5860 K) with a spill of 7020 K. The neutral white version is specced as 4500-5000 K.

The beam is wide with a hotspot. Spill angle is 116° and spot angle approximately 31°.

There is no PWM.

Measurements
Please note: lumen measurements are only rough estimates

My diy integrating styrofoam box cooler has been calibrated using a Fenix E05 on high with manufacturer’s claim of 85 lumens. Verified with an Olight S10 that has been measured with a Labsphere FS2 integrating sphere by valostore.fi. Results may be more inaccurate with especially throwy or floody lights.

For spectral information and CRI calculations I have an X-rite i1Pro spectrophotometer with HCFR for the plot and ArgyllCMS spotread.exe for the data. For runtime tests I use spotread.exe with a custom script and a i1Display Pro because it doesn’t require calibration every 30 minutes like the i1Pro.

Explanation of abbreviations
CCT = correlated color temperature, higher temperature means cooler (bluish)
CRI (Ra) = color rendering index consisting of 8 different colors (R1-R8), max value 100
CRI (R9) = color rendering index with deep red, usually difficult for led based light sources, max value 100
TLCI = television lighting consistency index, max value 100
x,y = coordinates on a CIE 1931 chart

Thanks for the review and testing.
So a negative R9 value for the XPG2. I’ve been reading up on the importance of R9. Since it is the measurement of red, important to certain indoor lighting that some utility companies give rebates if a products R9 value is zero or higher.

My Tiny has just arrived. I already hate it Sad
The light itself is good, but I have ordered the 90-CRI variant. I expected some nice white light. I received a “yellow” light (low colour temperature). Yellow, like the setting Sun Sad

I think, next time I will stick with the neutral white Smile

Anyway, what are those small ping gaskets for, what came with the light?
