This price (at just under AU $50, delivered) is a good deal.
I bought one in March discounted to around AU $70 delivered which was the best price around at the time. It took a month to arrive, so this is not likely to be suitable for urgent requirements. Alternatively I found the S10R selling a the moment on a few .au websites for $69.95 plus $7 to $8 delivery.
The S10R page will list at around AU $79 (which varies with the AUD-USD exchange rate). By applying the BGDS10R coupon in cart the price drops to the price in the title.
This LED torch/flashlight is high quality, small, powerful, uses one Li-Ion RCR123A battery and is easy to use. It can be recharged without having to remove the battery, which was a key feature for me. However the battery can still be removed and replaced in the typical way if required.
It is rated by OLIGHT at 400 lumens for 0.8h in high mode. There are three less bright and longer run-time modes. For my purposes it has ample brightness and throw indoors, outside the house and on city streets. In the house I often use "moonlight mode" which is easily accessible (a long press of the on button). It is 73.5 long x 23mm diameter. That is in the "thumb sized" league and "easily pocketable" would be an understatement.
In competing products, the Nitecore EC11 is a similar size and is rated by Nitecore at 900 lumens for 30 min. It achieves the increased output partly by using an IMR18350 battery which is similar sized to the RCR123A but can output at a higher rate of current. It does not have built in recharging. It currently costs over AU $70 on Banggood and was a much better price when they had an "email only" special on it when it was first in stock.
If a step up in power and battery size (and hence overall size) is required, I would choose the Nitecore MH20. It is 105mm x 31.8mm x 25.4mm (length x head x body diameter). It is USB rechargeable and is rated by Nitecore at 1000 lumens for 2h with 1 x 18650 battery. I noticed in the Q&A section of the MH20 page on Banggood they put up a coupon "438a6e". In cart that brings the price down to US $54 (~AU $79.28) incl. delivery. My web search didn't reveal any other MH20's under AU $100.
NOTE: The BGDS10R coupon appears to be valid from 1st June to 25th June. If so, there is only a few days left on it.
@gizmojo, +1 for your research and write up effort from one light fanatic to another.
Personally I've already got enough torches (ranging from $5 cheapies to high end $$$, battery types ranging from AAA to 2x18650 or 4xRCR123A) to see me thru a zombie apocalypse, this is very tempting but my missus says 'NO'.
Unless I come up with a REALLY good excuse…
