Official 7XRE LED Canister Primary Light Introduction

[TecDiveGear]

Hi everybody,
I've received a lot of emails about Light For Me lights, some of you were sent to the Americas distributor: 7XRE Technical Light and checked the specs out there but some still ask through ScubaBoard so I decided to open separate threads for each model where they gonna be introduced plus questions will be answered so, there we go ...

MODEL: 7XRE - 35Watt / 3600 lumen

About the light, technical specs:

Excellent for:
technical diving
recreational diving

Materials:
Made from anodized aluminium (tougher then machined delrin)
with laser engravings

Used Optics:
7 x CREE LED's giving 3600 lumens
LED's made on special order
light collimators with scattering angle of 4-5 degrees
providing a very narrow beam of light
colour/intensity of light - cold white 7000 up to 9000K corresponding to HID

Controlling Electronics:
Convienient rotating magnetic switch located on the lamp head
controlled by a microprocessor

Light offers 2 types of work :
- center LED working only or
- all LED's working

Constant supervision over the LEDs' temperature

Charger:
Microprocessor charger fed from power 100-240V grid 50-60Hz

Set of batteries:
Sealed set of NiMH power cells with 24V supply voltage,
set is made from only high quality cells.

The cylindrical batteries container allows outer charging (without opening the canister) and is equipped with pressure fuse and moisture absorber for advanced safety.

Available Burn time options:
5 hours burn (100% power)
3 hours burn (100% power)

very interesting thing is that when the power drops the light slowly dims out outer LED's ring to the center LED only to still provide maximum lumen output available (it happens after the max burn time with 100% power was used)

Test in pressure chamber: 10bar / equal to 300ft depth (nominal, during the tests first signs of structural changes - only with canister - were noticed between 40 - 50 ATA)

There are video clips available showing in water performance, few different dive spots with different conditions. Clips here:
YouTube - LightForMeUSA's Channel

Product designed and made in EU - UK/Poland
by
LIGHT FOR ME
Light-For-Me :: Diving Torch Lights

Comes with full 2 year (excluding batteries - covered for 6 months - are consumable) manufacturer warranty and service provided in US & Canada by TecDiveGear.

Dive safe,

From their original site there is a lot of discrepancies - could you explain them please ?

LIGHT-FOR-ME

Light-for-me 7XRE TECHNICAL TORCH

Made from anodised aluminium with laser engravings.

Produces 2200 lumens

Optics:
7 leds, 6-degree beam, very narrow light
Electronics:
2 independent converters2 ways of light; first - one led 5W, second - 7 leds 28Wsupervision over the LEDs' temperature
magnetic switch controlled by a microprocessor

Charger:

The set includes microprocessor charger fed from power 110V - 240V which allows to use it in the USA or Mexico
The cylindrical batteries' container is also made from anodised aliminum with laser engravings. It allows aouter charging wothout opening the cannister and is equipped with pressure fuse.
Dimensions and weight:
head diameter: 90mm
head length: 54 mm
battery cannister diameter: 70mm
battery cannister length: 280mm
light diameter: 70mm
weight on surface: 3,6 kg
weight under water: about 3kg
Battery pack:
24V NiMH battery pack

if there is in series (6 x 3,7V + cca 2V driver2 )(on/off) + (1 x 3,7V +cca 2V driver1 )(on) = 24,2V + 5,7V driven parallel -could be


Burntime: 5h

Housing:
The battery pack canister is made from anodised aluminium with laser engravings. In the upper lid there is a hermetic charging point - this type of the torch can be charged just by connecting and plugging the charger, without removing the battery pack from the canister.

what is with battery temperature monitoring during charging ?
How can be battery replaced?

In the lower lid of the canister there is a pressure fuse protecting from excessive raising of the pressure inside the canister (eg. in case the battery pack gets broken) and a moisture absorber that absorbs any moisture left in the canister.

moisture absorber - must be checked each time and dryed , them must be canister regulary opened ? Also pressure valve can fail ?
The set includes also a protective codura cover for aluminium canister that allows it to be attached to either wing or tank belts.

Test in pressure chamber: 10 bar

Best Regards

Does the battery pack have two separate lids, one for the charging point and another to access the battery? Can the magnetic switch be pulled or fall off? Can you posts pictures or a video of it being opened up?

How can you possibly get 3600 lumen from (7) XR-E's ? Each one is only rated for 220 lumens or so which would be 1540 lumen.

Did you forget, that LFM fit only " LED's made on special order "?

Well of course I can, its not a mistake.
Let's get started:

Produces 2200 lumens ?

As you know we have different units and measuring system in Europe and US, well it happens that there are not one but few slightly different ways and techniques to measure the lumens, footcandles, luxes, candlepower, brightness etc. In Summary all for measuring lighting efficiency work ...

To make the story short, in order to give US customers tool to compare the light output we've measured them the same way (same technique) as our US competitors so you as a potential customer will have fair and clear comparison.

Now something to check without the numbers, technical data for
35 Watt HID Light Monkey is served as "35 Watt HID with 3000 Lumen Output @ 6000 Kelvin" and you can clearly see on the vids that 7XRE is brighter with bigger lumen output so whichever system we will use 7XRE gives more lumens then 35 Watt HID.

2 independent converters2 ways of light; first - one led 5W, second - 7 leds 28Wsupervision over the LEDs' temperature

Same thing, just more of a technical language. Simplified: rotating switch providing 2 types of work: 1. center LED or 2. all of them

if there is in series (6 x 3,7V + cca 2V driver2 )(on/off) + (1 x 3,7V +cca 2V driver1 )(on) = 24,2V + 5,7V driven parallel -could be

Well we don't feel like we have to share that technical data with anybody, that and other solutions Light For Me have used just make our lights very good and competitive. If you're interested how its made I suggest you to buy one of those and take it part But remember, technology is patented

what is with battery temperature monitoring during charging ?
How can be battery replaced?

Charger is equipped with battery temperature monitoring wire.

Battery can be replaced by user but it is recommended to get it done by authorized service facility in US or worldwide.

moisture absorber - must be checked each time and dryed , them must be canister regulary opened ? Also pressure valve can fail ?

No, you don't have really a reason to open the canister, all you do is charge the light through charging port and use. This way the battery canister is properly sealed all the time. If with any reason pressure fuse will go off then it needs to be checked by authorized service facility in US.


These are good questions and I'm glad that I could answer them all.

Don't know whats your knowledge about todays LED's market but in this matter
Please contact

Cree, Inc.
4600 Silicon Drive
Durham, NC 27703

for any technical data about available LED's and produced lumens.

Thanks

Did you forget, that LFM fit only " LED's made on special order "?

I'm glad that you have fun but I'm the one who is really smiling right now.

Cree Inc. (American LED's Manufacturer) provides wide variety of customization depends on the needs. Light For Me buys more XRE, XPG, MC-E type LED's (good and pricey ones) then any other dive light manufacturer.


Thanks, have fun and dive safe !

I already have the data sheets from Cree which is why I made the above statement. Your claims for this product aren't accurate. No offense (honestly) but your technical knowledge of leds is not very good. This is probably a well made light but when you post lumen ratings and throw around wattage numbers that aren't (can't be) accurate it would be better to just leave that info out if you don't understand it yourself.

Looking at a 35 watt HID and visually determining that your light is brighter and therefore must be 35 watt and more than 3000 lumen is just totally flawed as an approach.

By the way a lumen is a lumen whether it's measured in the US or in the EU. It can't be 2200 there and 3600 here.

If you want to say "In our opinion our light is just as bright as a 35 W HID" then that's another matter. That's more like saying "In our opinion Corn Flakes is more tasty than Raisin Bran".

It is obvious that you have no idea of the technics that you sell.
But you can tell great stories!

Its nice to see that in your company is 7 x 242 Lumens = 3600 Lumen.
Fortunately, you have a patent on this technology

With such pretensions do you make yourself ridiculous.
