GUE-Style Backup Dive Light Under 50$ or Less

[@chrisraneri5195]

Hey Ben, Great review. Can you give your opinion why you chose to review the SecurityInc DF08 (rated 1000 lumen) vs the DF01 (1500 lumen) ?

[@DoktorBEN]

Well…that were the lights they sent me.

[@janinacooper4199]

Really neat alternative to the rather pricey options. Thank you for sharing!

[@DoktorBEN]

I bet all other backup lights (maybe except Heser) come from the same Chinese manufacturer 😄

[@Dutchtechdiver]

I think I’m using the same backup light since 2018. I think it sold with a lot different of names. I bought one in 2018 (30 euro AliExpress) and I did >100 tech dives and also cave dives. I did also use it at a 3 hours dive at felicitas when my primary light had a failure. I did like this light more then the heser. Burn time is shorter then my heser, but much more light with 26650 batteries. Brenda de Vries is also using one and I think she did use one at 100 meter or even deeper.

[@DoktorBEN]

Yes, I think they’re all produced in the same factory 😄

[@sorslibertas]

Hi Ben. Did you manage to test the burn times with LiPo vs alkaline batteries?

[@DoktorBEN]

No not yet…but thanks for the reminder

[@jensbiegert6337]

Great review. I bought two as BORUiT XM-L2 LED for 39€ and use them as backups for about a year in cave dives. I like the robustness and simplicity. No knobs etc as you said.

[@DoktorBEN]

Yes, knobs are just annoying 😄😄

[@dirkrosemann1123]

Schönes rewiev. Wo kann man die Lampe beziehen 🤔

[@DoktorBEN]

In der Beschreibung gibt’s einen Link

[@elvincecodilla2862]

I do hope you'll do a review on some OEM lights as well.. happy to hear about your honest review on some alternative light options. 😊

[@DoktorBEN]

Thanks! Do you have a particular light in mind?

[@elvincecodilla2862]

Yeah, x-adventurer m650 back up light.. I had the same model but from an unknown brand.. it's basically like a clone.

[@DoktorBEN]

I can try to get this one

[@elvincecodilla2862]

@@DoktorBEN wow appreciated it.

[@smartnotangry]

Personally I like the attachment with a line more then directly attached to the bolt snap with some kind of ring or something, because in case of a emergency the line can easily get cut through.

[@DoktorBEN]

Yes I do the same. Metal-to-Metal-connections are not recommendable

[@spaceman61]

I bought the Heser …… like you said …

[@meandtina]

HI Doktor Ben, I went out and got one. Very similar except it didn't come with the tube for 18650 batteries, so I have to use size C battery (3 pcs). Very very bright for the price that is under $50.

[@DoktorBEN]

You might even make a tube yourself! Doesn’t seem too complicated

[@meandtina]

@@DoktorBEN Update on the light, the batteries are 26650, not 18650. 2 pcs. of 26650 batteries for the handheld backup light, and 3 pcs. for canister light. Pretty decent performance.

[@DoktorBEN]

Oh yeah! And you don’t need a tube!

[@juanpereira6258]

Hi Ben- Do you have any review of the NAUTEC valve made in Germany?

[@DoktorBEN]

No, not yet. Which one do you mean exactly?

[@juanpereira6258]

@@DoktorBEN Nautec - Tec Valve Trim M25 - Air 230 / PRO Line Thanks Ben for your support

[@DoktorBEN]

I see what I can do!

[@asty3841]

Does the attach point for the rope has a smooth surface? It looks like it has sharp angles, that could damage the boltsnap attachment.

[@DoktorBEN]

No, it has no sharp edges

[@spartanthe300ththermopylae4]

@asty3841 you can smoothen the edges with a dremel (or even with a small hand file).

[@frankborelbach8938]

Genau die gleiche Lampe habe ich von Scubaforce 😄

[@DoktorBEN]

Ja ich denke die gibt’s noch von ein paar anderen Marken.

[@dirkrosemann1123]

@@DoktorBEN Die TECLINE Tecline Backup Lampe US 16 sieht verdächtig ähnlich aus 🙂

[@DoktorBEN]

Ja sicher…Tecline produziert die ja auch nicht selbst sonder kauft die zu. Die Lampe von Scubapro findet man auch exakt so mit zig verschiedenen Markennamen.

Super Video, vielen Dank für deine ausführliche Review. Sehr gelungenes Videos! Werde mir die Lampe über deinen link bestellen. Kannst du mir einen Link für deine favorisierten Batterien auf Amazon zusenden? Liebe Grüße Jan

[@DoktorBEN]

Vielen Dank! Für welchen Akkutyp?

[@janthomas4090]

Den besseren, welchen du favorisierst ;)

It is anodized aluminium

[@sandibracko4175]

You talk about 18650 LiFePO4 battery which gives both nominal 6,4 V but you have in hand LiOn baterry which gives 7,4V . because of different chemistry. If I chose I would take orcatorch orcad 520D it cost little more than 50$ but still in range. These backups made front heavy . IMO mixing LED as light and alkalines is equal as using electric car with Pb bateries ..it works but it is pointless . More important is battery self - discharging time

[@marcin.j.wasiak]

This is GUE standard of using alkaline batteries coming from early 2000's when rechargeable batteries were Ni-Mn and had poor reliability and charge holding time. GUE did not update this standard with advantages of technology making it cult-like item, same for any "H" branded items. Here DrBen would be better source of information. I like the versatility of this light accepting variety of cells and voltages (similar to Shearwater computers).

[@DoktorBEN]

GUE keeps the standard for very good reasons, despite batteries have largely improved. Still, I like that this light is flexible!

Snubbish way to clean the o ring by a piece of toilet paper 😂
