SOLD: The "Ginormous Bug Eye" - Huge 100W LED emitter based flashlight

[rhd]

For info, check out this thread:
http://laserpointerforums.com/f66/ginormous-bug-eye-100w-led-build-72191.html

This is one of a few items that I need to sell before moving next week. It's cool, but it's a novelty for sure. Most crucially, it's rather heavy, and I'm pushing my weight limits for the move as it is.

I'm basically going to sell it for less than the price of the 100W LED emitter in it. $40 plus $10 for shipping takes it. So $50 shipped to anywhere.

Before you guys ask, sorry, I can't sell you the 14250 lithium ion batteries, we're not allowed to ship lithium ion batteries in Canada.

That's strange....
Where did you get the 14250 batteries...

I seems that Onlybatteries.com can ship them in Canada from
a Montreal location or even from the USA to Canada...:thinking:

I've received plenty of Li-Ion and Li-Po batteries with no problems...

3.6 Volt 1/2 AA 1200 mAh (LS14250 and ER14250) Primary Lithium Battery

Is there a new law that came out that I'm not aware of.... :thinking:

Apparently

CanadaPost regulation 3.2.2.7
Canada Post - ABCs of Mailing - Personal

3.2.2.7 Batteries

Lithium Batteries
All of the following requirements must be met when packaging Lithium Batteries. They must:

- be shipped within Canada
- be shipped by surface only using Expedited Parcel™ service or Regular Parcel™ service
- meet the conditions outlined in Special Provision 34 (2) of the Transportation of Dangerous Goods Regulations.

And for simplicity's sake, here is Special Provision 34 (2) of the Transportation of Dangerous Goods Regulations:

(a) each cell with a liquid cathode contains not more than 0.5 g of lithium or lithium alloy;
(b) each battery with a liquid cathode contains a total quantity of not more than 1 g of lithium or lithium alloy;
(c) each cell or battery with a liquid cathode is hermetically sealed;
(d) each cell with a solid cathode contains not more than 1 g of lithium or lithium alloy;
(e) each battery with a solid cathode contains a total quantity of not more than 2 g of lithium or lithium alloy;
(f) each lithium-ion cell contains a total quantity of not more than 1.5 g of equivalent lithium content, where the equivalent lithium content in grams is 0.3 times the rated capacity of the cell in ampere-hours;
(g) each lithium-ion battery contains a total quantity of not more than 8 g of equivalent lithium content, where the equivalent lithium content in grams is 0.3 times the rated capacity of the battery in ampere-hours;
(h) for a liquid cathode battery that contains more than 0.5 g of lithium or lithium alloy or a solid cathode battery that contains more than 1 g of lithium or lithium alloy, the battery does not contain a liquid or gas that is dangerous goods unless the liquid or gas, if free, would be completely absorbed or neutralized by other materials in the battery;
(i) the cells are separated to prevent short circuits; and
(j) the batteries are separated to prevent short circuits and, except when they are installed in electronic devices, are packed in strong means of containment.

So, in some very limited situations, you can still mail lithium ion batteries from Canada to other Canadian destinations, but even then, you have to use one of those two services (Expedited, or Regular), and your cells have to meet the really restrictive criteria from the TDG act Special Provision 34(2).

Long story short, there is no way to mail a lithium ion cell from Canada to an international destination via Canada Post, and even mailing within Canada is prohibited for all but the most incredibly small cells, as per TDG Act Special Resolution 34(2).

WOW I missed it... How was the light? Was it throwing far?

 

[lasersbee]

But mikeox does live in CANADA...
So the Li-Ion batteries just can't be shipped by Air...
but Ground is doable...

Thanks for the links...:beer:

BTW how much lithium is in a 14250 cell....:thinking:

Nope, because they have to meet all three requirements of 3.2.2.7. So they certainly couldn't go air, but they would also have to meet SP 34(2).

It's hard to find specs as to the amount of lithium per cell, but you can calculate rough estimates. The specific energy range for a li-ion is 100 to 250 Watt hours per kg.

A cell like a 14250 probably has around 200mAh, which implies roughly 750 mWh per cell. So depending on where in the range of specific energy this cell falls, it would need between 3 and 7.5 grams of lithium.

No matter where you fall in that range, it's far outside the allowances in SP 34(2). Essentially, those allowances are probably there to allow for shipping of watch and hearing aid batteries - ie. small button cells.

Wow rhd, that amount is unreasonably high for one battery of this type, and for the data that I know.

A 18650 battery of 2000mAh has approximately 0.6gr amount of lithium content.

This means that a battery of 200mAh contains about 0.06gr of lithium per battery.

Then cite your source sir Here's my process:

Lithium ion cells have an energy density of 0.72 MJ per kg
= 211 Watt hours per kg
= 0.211 Watt hours per g
= 211 mW hours per g

Then we need to know how many mW hours are in a cell.
= 200mAh * 3.7V
= 740 mW hours

Then to figure out the gram figure:
= 740mW hours / 211 mW hours per g
= ~3.5 grams

You have to consider that there is no metallic lithium in a typical lithium-ion battery (I know you know this, of course),
but however this is the equivalent lithium content that must be considered.

An example, can be considered that approximately 8 grams of equivalent lithium content are equal to about 100 watt-hour,
that means we need a battery with (appox) 9300mAh at 10.8V to reach that amount, and that is very different from your
small battery of 200mAh at 3.6V and 3 - 7,5gr of lithium.

To give two examples where you can get an idea.

How many lumens of light did this output?

Dumb question:

Couldn't you just ship the batteries via private shipping company like fedex, ups or dhl?

Actually, I think that is a good question!

Yep, I don't think that would be a problem -not entirely sure.

Awe. This was a good deal. Wish I was around when you posted this.
