Sunlite Eagle 8W Far Projection - Review - With Outdoor Beamshots

Candle Power Flashlight Forum

Help Support CPF:

Here are a few pics of the emitter. Glenn is right, there is no dome. That's why the light source is smaller than all other emitters. It is not packed in a 5mm dome. Emitter is 1.5x1.5mm.

Glenn, I played around with the settings....the lowest my iso would go is 200, but my f stop went to f32. I had to put my shutter speed on 8000 because there was just too much light getting in.

Because my originals were over 2mb, I did a screen capture which turned it into a reduced quality gif. But this is the gist of what the emitter is like.




Edit: I was able to get a decent shot through the welding lens Glenn!:poke:😀

Nice shots my camera could never take photos that close even when i use maco mode.
 
Why can't people except the led is sunlites own and not osram,cree or seoul :poke:


Unless they buy just the led wafer and mount it on a copper slug,but that would not make much sense.:shakehead



BTW guys sunlite are going to make a forward clicky tail cap in a couple of months,just show your interest on the sunlite forum and that means you as well Glenn :poke:

From the emitter pics Ryanrpm published I saw something. I processed the last pic in post 122:

It's visible in the original pic too, but here it stands out. I belive it might be an emitter that use multiple dice. Mind that I don't have the light or even one of the emitters. I have also not been able to find specs for the emitter so I can be off here.
 
It's intriguing. I'd like to see some specs on the emitter, it would be spectacular if an 'unknown' manufacturer just showed up with stuff spanking the big names. As it is it seems a bit too good to be true (that they have their own unique emitter). There's no doubt about the fact that it's a powerful emitter though.

According to their website they've been making LED's for more than 10 years.
 
This quote from wiki...
An epiwafer is a wafer of semiconducting material made by epitaxial growth (called epitaxy) for use in making microelectronic devices such as light-emitting diodes (LEDs).


So if they have the manufacturing capabilities for making epi wafers it seems reasonable to suggest they make their own leds,also they say they have been doing this process since 1997.


The main thing here, it's nothing new it's just that they can do it all in house that's how I read it.
 
I guess it would be more accurate to call their LED's this:

"Sunlite AS-LED's"

Got this from their site:

Mar 2005 - Proposed the concept of AS-LED (Application-Specific Light Emitting Diode) and built the Slim LED head based on the AS-LED concept.

That is why, in this new 16w Far Projection light coming out in a few months, they can can make the dimensions of the chip a little bigger and give it more current. Every light is made for a specific application. Talk about flexibility! They have a technology totally unique to themselves and have the ability to surpass others. How else can they have a single chip emitter producing 500+ lumens? I'm not sure, but I think they even make their own batteries too. Look at the shot on page 1 I took of the battery. Has anyone seen anything like that before?
 
Yes the battery is unusual in that it seems like three contact areas i.e tail and 2 in the battery tube,I tried a 18650 and only the turbo works which make me wonder if one of the contacts is for switching :shrug:


If you look down the tube you can see a double spring one inside the other I guess for 2 contacts on the - end which could be for charging.

Stefan the die in the 8W wouldn't be quite twice the size of a osram GD - but it is tiny and real hard to photograph

the 8W die is mounted on a little round pedestal about 5mm high - the little round thing next to the die is a hole of which the tiny gold wires from the die go through - you can see this in the photos that i took - and may i say took a guts effort and time to take (think i will patent it ) nah! well it took two hands a spare light a magnifier a zoom lens my teeth and almost had to use my butt cheeks to take the shots

the photos are full size so you can play with them ie: zoom up to see the wires - enjoy http://picasaweb.google.com.au/glennkath/Eagle8WLED?authkey=4lonB_iH4qw#

I think the reason why they make the flashlight head so hard to open is because they don't want anyone to observe their LED too closely.
 
I got back a email from Fong about the battery here is a bit of what was said,
There is a safety control circuit PCB built-in on the negative side of the battery to protect the Li-ion battery if shortage ever happens, and also to shut off the battery when the voltage is too low or too high. It will also shut off the recharging when the voltage reaches ~4.2V.

Do not use 18650 without this safety control circuit PCB built in as it may over charge and cause explosion,best advice use only the batteries supplied 😉
