Designing a focusable LED dive light.

[SUBjohan]

I dont like such a system.
In this case i will change to another forum with better rules and present the pictures there.

Hi Michael,

You can e-mail the pictures to me if you want, I can upload them than to my website and post them here.

How about some information on how your focal system works Michael.
Are you using reflectors or optics?
After all this thread is about designing such a system.

I use an aspheric lens. With turning the front-ring (only 1/4 turn is necessary for 100% changing the beam) you get a light beam without any spill from 8° up to 36°.
The mechanic for focusing is uneffected from water pressure, the switch too.

Hello,

sorry, the first pictures are ready, but i dont find the possibility to attach them in the text.
The written rules in FAQ don´t accord with the practice.

Michael,

What do you mean? I always post pictures in my post (look at my signature). Photos can be added as text with the location enclosed in the HTML Image tags:
"[" + "IMG" + "]" + "actual link to picture such as http://location/picture.jpg" + "[" + "/IMG" + "]"

Example:

If you reply to this post with the "Quote" option you will see the http codes in the picture I posted.

Since this picture is from your own website, we are not breaking any forum rules. Here you go:

Try to quote my text in a reply, and you will see the http codes you need to put around the picture in order to have it show here directly.

This one is small and it is OK, but keep in mind the forum only allows up to 800x600 images.

If the pictures you want to show are in somebody elses' web site (not your own), then we can't link to them directly since that would be against forum rules and we would be unfairly be using that other web site's server resources.

Very interesting.
What is the diameter of the Aspheric?

Hi Will,

this is not the new VB-50 head, this picture shows the X1-VB, a primary backup light.

Sounding better all the time 🙂

If you are still having problems with images, you could create a photo bucket account, or use a similar photo storage website? Or email them to Johan who can display them for you.

Hopefully you don't do this as I'm really interested in seeing your pictures, as I suspect is everyone else in this thread! This is a dive light forum after alll, so I think you could be missing out on potential customers if you show your latest light somewhere else!

Maybe there is a chance of a discount for CPF members?

@ Packhorse
The lens has a diameter of 50 mm

@ all

Now i can present some details and pictures of our new LED-head VB-50.

Adjustable beam between 8° and 36°, without spill
Only a quarter turn for 100% adjustable range
Switch and adjustable mechanic is uneffected from water pressure
Max. brightness is > 20.000 lux
LED: SST-50 with approx 1250 Lumen
2 power-steps: 100% and 35%

The VB-50 is usuable as hand light (here with battery from our PHOTON). Burning time is 1 hr with 100% power setting and more than 2 hrs with power step 2.

I think the normal use will be with Goodman-handle.

The price for the head is euro 428,00 (incl. Goodman-handle) incl. 19% VAT

The VB-50 is available end of January.

Here are the next pictures:

The VB-50 is vailable with E/O cord too.

Glad that you got things sorted Michael those are excellent pictures! 😎 :twothumbs

Do you have a picture 'front on' that shows the LED and the lens?

What is the price of the vb-50 head with the photon body, and the vb-50 head with the photon2 body?

Thanks again for sharing.

@whitenoise

Sorry, but i dont have a picture of frontside😀

The price for the VB-50 head with the PHOTON body incl. the charger is euro 628,00 and with the body of PHOTON2 euro 686,00. The prices are include 19% VAT.

Great pictures - it is a beautiful light indeed :twothumbs

 

[whitenoise]

Thanks for that Michael. Have you done any beam shots of the light so we can see what it looks like in action?

It's more than I was originally looking to pay for a new light (especially with the very poor Euro rate at the moment), but interesting, very interesting. We currently have 15% VAT here in the UK, any chance of using that instead of 19%? 😀

Also do CPF members get a discount? 😀 😀 😀

 

[whitenoise]

Forgot to ask about what batteries you are using. Is it a battery 'pack' (if so what chemistry etc), or individual user replaceable batteries?

Thanks

 

[SUBjohan]

(especially with the very poor Euro rate at the moment)

[offtopic mode] You mean the poor Pound rate ? 😗
At this moment it is for us in the EU verry intresting to buy things in the UK and US 😀 [/offtopic mode]

We use only Lithium-Manganese rechargeable batteries. That is the reason because i have written include charger.

LED: SST-50 with approx 1250 Lumen

From MBsub website

The X1 - VB achieves an incredible signaling effect with the fully focused light beam of 17.500 lux.

The fixed focus version X1 - FF achieves an incredible brightness of 21.000 lux.

Am I reading the specs correctly in regards to the lux? It seems like the VB-50 isnt any brighter than the X1 which uses a XR-E LED ( I think)?

 

[mbsub]

@ Packhorse

Its normal, because the spot diameter of the X1-FF is approx. 5 cm (in 1 m distance)
and from the VB-50 is the feed size of the light square 14,5 cm.

That means, the light will be shared on a really big area in relation to the X1

The X1 has 3° and the VB-50 has "only" 8°, because the die of the SST-50 is much bigger than the die of the XR-E

BTW, here you can see, that we work with honest dates.
