This review is of the earlier version manufactured by Manker. The current A01 has PWM, 5000K emitter and a next mode memory
Astrolux A01 is a new waterproof mini flashlight that uses an AAA battery and a high CRI Nichia LED. Its maximum width is 16,6 mm on the head with a length of 72,7 mm. Weight is 16 grams without a battery and 29 g with an Eneloop. The light is available in black, silver and purple finish.
The light is available only with a Nichia 219B LED. Color temperature is just shy of 4000 K on an Eneloop and a tad higher on a 10440. The light is high CRI with a color rendering index of over 90. Color temperature stays consistent in the spill.
Switch is a twisty type. Changing between the two modes is done by switching the light off and back on again. After the second round the light goes to strobe mode (L-M-H-L-M-H-Strobe-L-M-H...). On my other sample the connection is not very reliable and the light sometimes flickers especially on the low mode when touching the light.
In addition to alkaline and NiMH batteries, the A01 works with a 10440 lithium ion cell too. On a 10440 the output increases to 226 lumens from Eneloop's 87. Prolonged use of 10440 battery is not recommended though, since the light gets very hot during use. With a fan blowing on it I measured the head at 47°C after 5 minutes. This is way too hot to comfortably hold with bare hands. With an Eneloop and no fan the temperature climbs up to 54°C after 10-20 minutes, which is also too hot for my hands. The fan lowers the temps anywhere from 15-20 degrees. The light gets cooler after some time as the output diminishes.
On an Eneloop the output is well regulated until to about 40 minutes after which the light starts to dim faster. Only the high mode works well with a 10440, on low and medium the output varies sporadically. There's no straight up flicker but sudden variations in output. An Eneloop worked fine after using the 10440, so the driver did not get damaged.
The beam angle is 83° with a hotspot of 27°.
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
