Review: Brinyte DIV03 (diving light)

Technical Specifications:    
Cost: ~$45   (TIS, ELB, Ali, Ali, Aura, eBay chinavally, eBay AU)
Construction:  T-6061-T6 anodized aluminum with gloss finish
Size: 130 x 51 x 40 x 42mm (length x head diameter x tube diameter x tailcap)
Imperial units: 5.1'' x 2'' x 1.6'' x 1.65''
Weight:  300g / 10.6 oz (w/o battery).  About 370g / 13 oz (0.8Ibs) with batteries
UI (User Interface): Twisty.  1 mode (Hi)

Powered by:  (3) AA Alkaline / Ni-MH / Energizer Lithium
OR  (1) Li-ion:  25500 (TF @ RTDAmzn) or *26500 (Efest sold @ FV, RTD, MEL, MVO, BJ); non Efest (AV)
LED:  (1) Cree XM-L T6 with smooth (SMO) reflector
Lumens:  500 (FL1 standard cf. link)
Current Draw:  2.8A (advertised)          
Burn Time:  ~2+ hrs
Working Voltage: 2.7- 4.2V
Depth rating:  120-150m (394-492ft)

This is a short and stocky dive light.  Length is about 5 inches, with a 2 inch bezel width.   Turns on by a simple twist of the head.   Has only one mode (Hi).  

This can be used as a primary light on short dives, especially for recreation divers.   For extended runtimes use Energizer Ultimate Lithium cells (L91).  These should give the longest burntimes (buy Amzn, Sams, eBay) (info:  HKJ review,   Datasheet)

I prefer to use a single Li-ion in the light.  This replaces the AA battery carrier.   Use a piece of cardboard to keep the battery from rattling inside (see pic 1, pic 2)
Haven't tried the Efest 26500 - which probably has a higher capacity then the 25500 Trustfire & Ultrafire cells I used.  But this was all I could find at the time. 
See HKJ's review of Efest cell  - actual amp draw will be close to 3 amps when you first use the light. 

Beamshot:  DIV03 vs. DIV01 (right side)
For comparison with Brinyte DIV05 (see Post mouseover

The Good:
Very robust light.   The wall thickness is thick giving it a solid feel.   It's also bright which is a must for me.  
Uses 3 o-rings where it comes apart, which should seal out water nicely.

                                                                         Can be conveniently attached to the hand for hands-free diving >

Comes apart in only one place - Very nice! - minimizes potential for water intrusion.

The Bad:
1.  Heavy at about 370g / 13 oz with batteries.  That's 0.8 Ibs.
2.  Runtime could be much better if they made this run on a single 26650.  It would be just about perfect if they did.  As it stands you'll get a good 1.3 hrs of bright light, then you probably want to change the battery.  
3.  The AA battery carrier fitted with some rechargeable Ni-MH cells won't fit back inside the light.  Some rechargeables make the overall thickness to wide and the battery carrier won't go back in.   My newer XX Eneloops would not fit - they make it too thick.  

These rechargeable batteries should fit:  Duracell, regular Eneloops, Maxwell, Sony.   I think the problem is that the battery carriers are not exactly the same.   Regular Alkaline cells fit fine.  

I would give it 5 stars IF (1) it ran on a single 26650 Li-ion battery as well as an alternative 3AA battery carrier. 
And (2) it was lighter by about 90 grams.   
Overall it is a very good dive light.                              

added a couple mouse overs (see pics)

Thanks for the review. Do you think an unprotected cell like a King Kong INR26650 would fit in this thing? I do have a couple of those on the way. Otherwise, I think I’ll stick to the original plan and get the DIV05 as my first dive light. Like you, I would prefer a single li-ion as the power source.

edit: checked that link on the efest. It’s unprotected too, so should be the same size as the KK. I’ll wait for you to test it out with that.

I tried to put the cell your talking about (unprotected flat top 26650 KK) in there and it wouldn't fit.  So I cut the rear tailcap spring and tried again.  It still wouldn't fit. 

But I managed to smash in the cathode end (+) of my KingKong. Frown   So 26650s don't want to cooperate in this light, but I tried my best Laughing


As far as the Efest batteries I mentioned... they will fit.  Their size is 26500 not 26650, which I think you were thinking.   Meaning the "nominal" size for the Efest is 26mm wide x 50mm long, and 0 = cylindrical shape.


BTW the inside tube diameter is 1.2'' (30.5mm) where the batteries go.
