Just ordered d10u through Amazon and received torch for scuba video and still recording application.
Unit is very well constructed and uses two o-rings for seal.
They supply two spare o-rings, but "supplied" silicone grease was missing from packaging.
Zoom is very tight, but no access to seal for zoom section.
Wide beam pattern looks adequate and fairly uniform except for slight bright spot in center.
Torch has high, low, flashing modes, all activates by successive twisting tail section.
Their other model D11v is fixed wide angle at 110degrees (suited for GroPro) and slightly brighter overall by 20%,
but at 68 degrees beam angle, this one should be brighter for general scuba photography.
Narrow beam shows square chip projection.
I will pressure test to 130ft diving spec to verify advertised design.
Uses (1) 18650 with built in protection circuit ...a 2100mAh (tested) battery last 55 minutes until "blinking", then another 10 minutes in low power mode. Battery after discharge showed 2.85volts, which is proper.
The unit at narrow handle gets quite warm on discharge. They claim 70 minutes which is quite likely with a 2650mAh battery.
Note: although listed on Amazon for $46.80 USD w/free shipping, was shipped from China and took 4 weeks for delivery.
Have not been able to find a US distributor online or on eBay. Prices vary by as much as 3x.
I choose Amazon, so if I had any complaints, there is someone to complain too that might make it right and I didn't want to give
a company in China my CC number for security reasons.
If anyone has further interest, I will post photos of inexpensive camera/torch bracket for underwater photography.
