9090 LED's (6x) in dive light - what are they?

Obviously there is some sort of typo ;-) in those figures.

Totally smells like out of order light quality in those torches, could it be?

Cheers :-)

I had such light and it leaked on a first shallow 15m dive.
Salt water killed everything :frowning:
It’s a lottery, some of my friends use it and they are happy….

So, did you have fun? Maybe some teflon tape…

What is the actual effective throw of it? Not now, I mean, when O:) working. 15 meters?

Same trouble here. My leaked after 5 dives.I was able to save mine and found the the switch is poorly designed and allows water in.

I bought another light 6LEDs 9090, slightly different body style , more like one pictured with camera on previous post, and I took the switch apart and noticed that this light has improved switch. They added another silicone membrane to stop water from ever coming in contact with button shaft.

I use two of these , have about 40 dives with them up to 30m and so far so good!
Very bright, but fairly small and in comparison by far cheapest out there.

I am looking at https://www.amazon.de/dp/B07FTHDDXN/ref=cm_sw_r_cp_apa_i\_.rDoEbNPY39F9

I see that theres a link to taobao but i can’t translate reviews… Is it worth 60€?

RokSiEu, that looks like another leaky piece of junk with overstated specifications waiting to make your day.

I would rather buy a flashlight designed and built by a real manufacturer. Sofirn has many diving torches, for example (but better look for reviews before buying, like this Sofirn SD05 review by Nachtfeuerzeug). ThorFire, another nice brand, has its ThorFire S1 diving flashlight recommended at GloboSurfer as a best pick.

Anyway, feel free to ask but wait for more experienced users in these concerns to chime in.

If you are looking for powerful light with wide angle beam , check the link below. I bought two of these and have about 60 dives with them and so far they perform well. Very reasonable price

Is it blue or UV?

Do you have some pictures or videos taken with those lights? Can it be mounted to gopro holder?

Try this link , all details are listed .
I used model that has 6x 9090LEDs , those blue/uv leds really work for corals with neon colour.

Video taken with these lights.

They have 1/4in tread so you can fit attachment to suit your need.

Rec diver, your above #15 post includes a link full of unnecessary tracking information, all which comes after the question mark and the question mark itself is better removed.

The link can in fact be further simplified by removing the information between the itm string and the article number:

https://www.ebay.com/itm/-/233224259249

However, the reason I'm telling you this is because the excessively long link you posted breaks the forum page layout, as it exceeds the thread box. Could you please edit your post and replace that link with one of the above? Thanks.

For illustrative purposes:

Amazing video, which camera are you using?

Panasonic GH5

Sorry, link fixed. I hope it still works.

It does, tnx for the tip, now I’m just thinking if I should go for the one with more LEDs as most of the dives are done in mediterranean sea where we don’t have such great light conditions as in Carribean

I do believe that the 6x9090 LED model produces more light ( they claim 500W, probably less but very bright)
The light you were referring in your first post have 15 smaller LEDs but they rate these (120-180W equivalent) which would mean a lot less light produced. The 9090 LEDs are some of the most powerful out there.
The model with six 9090s have burning time 45min at full brightness with good Panasonic batteries.
With three modes you can easily adjust desired brightness and on low batteries will last more than 80 min.

That is what I wanted to hear. Thank you

See this Scubaboard thread for more information on these lights - ‘Cheap Chinese Video Light’

A chap reviews the differences between the A11, A15, A10

I have the A15 and find it very good. From the other posts in the thread though I am wary about the clicky switches failing after more than a few dives.

As I posted in that thread, has anyone had any experience with the new type popping up now? COB Led versions

Only ~£30 i’m tempted to pick one up.
4 x 18650 as per the others, looks to be the same chassis just with a different led.

‘uranusFire’

‘Brett’

The LED is a COB type - can’t find any information as to which one.

Im curious to see if this is more powerful / has a different beam profile to the 15 x XML-2 variants

EDIT: I have started a new topic on these COB lights here

Hi RokSiEu,
as I mentioned on ScubaBoard, these lamps come with different names, check this: https://www.aliexpress.com/item/33011130681.html
Between QH15, and QH14-7, the more powerful is QH14-7 (also pictured in post #8), and QH15 has a warmer tone. My tip would be to buy 2 and mount them on a plate on bendable arms, or not fully screwed in, thus have them able to turn.

On Amazon (.de or .fr), QH15 is below 40 EUR. Cheapest is the QH18 variant: Amazon.fr . (BTW, Chinese prices on 1688.com for almost all these lamps are like 10EUR /lamp, but you have to buy quantities (10 was too little from one supplier, although they advertised you could buy at least 2; it seemed they wanted to test me, so I gave up). You could buy 2 of these, and be below 60 EUR; for the total ~10K lumen underwater, it’s unbeatable.

On my YT channel (subscribe! ;-)) you can see how the QH15 (on the left) and the QH14-7 (on the right) look underwater:
2019.07.05 - Egypt - Hurghada - Gota Abu Ramada D2 - YouTube , with a simple go through all modes of use (and with white light + red)
2019.07.06 - Egypt - Hurghada - El Fanadir North D2 - YouTube , you can clearly see the difference in light temperature on the sand, without filter
2019.07.06 - Egypt - Hurghada - El Fanadir North D2 - YouTube , same video, with Backscatter “Dive” Red filter, QH14-7, since it’s cooler, the red filter doesn’t make the image too yellow, and you can use with the filter to get more colors in the background /more distant).
2019.07.05 - Egypt - Hurghada - Gota Abu Ramada D2 - YouTube , here you can see, the Red and Blue Leds in action (with and without the “Dive” red filter).

But all the QH series need a better driver; the lights flicker when being used at 50% and 25% power settings : 2019.07.06 - Egypt - Hurghada - El Fanadir South D1 - YouTube , flickering at 13:35.
In almost every video in the “Hurghada 2019” playlist I used usually the QH15 and QH14-7, but also the QH18 in the first 2-3 days (forgot to write down which was which), so pick any video, and go through the playbar until you find something interesting to see, and make a choice.

I actually think it’s somehow the same base-design as the BLF Q8. Maybe we could change the driver and make them much more powerful. A mod for the buttons, like unscrewing, gluing some additional membrane, and screwing back on wouldn’t be inconceivable.

Lexel, since you started the BLF Q8 thread, would you be interested in taking a look at these? Either by aquiring one, or having one sent to you by one of us? Maybe Mieciu and Rec diver, who’ve had broken lamps could disassemble theirs and post some pictures?

What do you people think?

I’ve just received my light from amazon.de , expencier than other sites but 1 year warrenty is worth it.

I hope I’ll try it next week in Croatian sea.

Are you using gopro? Which macro addon? Which holder?

Regarding mods, let me know if I can help!

I am using GoPro 7 Black with the Backscatter Flip 7 Kit. It does it’s job nicely, but I wish I would have searched more before, it has some design flaws, which you discover in use, and there are cheaper similar versions available.
