Cheap Chinese Canister Lights :)

[Dominick Gheesling]

Hello,

I recently purchased this light:

Underwater 150m 10000lm 6x L2 LED SCUBA Diving Flashlight Torch Light+Bracket | eBay

So far I have used on a few dives at Madison Blue and Little River. Seems extremely bright. Wondering if anyone else out there has purchased this model as I am unable to find replacement o-rings. Don't need the o-rings yet, as it came with a spare set but at some point I'll be needing some. Thanks for any advice.

What type batteries? What burn time?

What type batteries? What burn time?

Uses three lithium batteries: 18650

Estimated Burn Time: Over two hours on Max setting

Just a couple thoughts...

-I don't see the point in the cord/can with a light this size. A dive rite LX20 uses 4x18650 and effectively combines the battery pack into a HH unit. I don't see the can/cord as worth the effort for this size light. ....now if you need a can light for a tech cert requirement, the. Maybe this is a good cheap option.

-mak sure you don't get any "flicker"from that battery pack if you bump or shake it. I have a similar pack on a Hollis light. I now out a quick wrap of electrical tape around the batteries to prevent any movement.

-watch the o-rings carefully. I have had two "cheap" lights flood on me from o-ring failures. Best bet is to use a digital caliper and try to fine a match. Or maybe even send an old one into an oring supplier to see if they can match it.

Nice...I am always skeptical about chinese crap, but I am a skeptic. Be careful charging the lithium batteries, charge them outside or at least when charging keep a CLOSE watch over them.

Have not noticed any flicker but that is a great idea to wrap with electrical tape to avoid it.

For that lumen output the canister is really not worth it. I have a Big Blue that is 1100 lumen runs on one of those batteries with the same burn time that I use as a back up.

Run 6 x Cree XM-L2 emitters at full power, from 3 x 18650 batteries, for 2 hours. No way! I'd bet real money that it's either only putting out 2000 lumens (or less) or the burn time is less than 1 hour.

At something like full power, a single 18650 will run a single XM-L2 for about 90 minutes. 3 batteries to run 6 LEDs is going to be way less (unless they aren't running anywhere near full power).

I have the exact same light and use 3 x good quality 3400mah 18650's (capacity verified by me). It will run for about an hour and a half at full power then low power mode kicks in and it'll run for around another 20 minutes at 25% brightness. There's no flicker as long as I use button top cells, I did try flat tops and did get the occasional flicker.
I never dive with it above the 2nd power setting and usually use it on the lowest as it's just too bright when there's particles in the water. One set of cells easily sees me through a couple of hours diving using these settings.
Re the 10,000 lumens claim; its probably more like 5000 which is still incredibly bright. I have a 500 watt halogen floodlight in my garden and this cuts through it easily.

I ordered a HH Chinese light that holds 6 18650 batteries and gets 6 hours on high output and 23 hours on low. Claims 10000 lumens but we all know that's not real. However on low it's more than bright enough and I've had no leaking as long as I keep the O-rings greased.
