Lamina 260lm led

[James]

Has anyone come across www.laminmaceramics.com?
They have a white led p/n NT-42D0-0426.
Takes about 7.6VDC and up to 1400mA.
at 700mA it puts out 175 lm
at 1050mA it puts out 250 lm
(that's about twice the luxeon k2!)
Digikey sells them for about $15.50.
Has anyone tried one of these?

I think myself and a few others have played with them a bit. Good and bad, all things considered they are ok.

[Enolmano]

you missed an "a" in the link :)
http://www.laminaceramics.com/ should it be

[james3]

And I thought he just added an "m". :P

at 250 lm, how can that be bad? Only downside I see is that no one seems to have them in stock, but then again, it's the same with the K2's as well...

I think it'd be a simple matter of adding more tapped holes to the MHS Heatsink to mount one of these. After that, just drive it off a buck puck, right? There might have to even more holes for the optics mount, and a little more space in the emitters to accomidate the larger optics...

There not in stock because they have not been released yet. If it requires the same fraen lens that the other ones they offer does then it will not fit in the MHS holder, so you will have to make your own heat sink and blade holder and hilt to make it fit.

[Dregan]

A truly wonderful addition to the MHS would be an emitter/heatsink for this LED. At 250 lumens, there's gonne be a lot of people that want to use it. Myself included. If Tim makes a part to fit these bad boys, I'm officially calling dibs on the first one. If not, I may hust have to ask him to custom do me one...

Note - I found the PDF that has the form factor for these things. Man, do I wish I had a lathe/mill right now...

There also 10 and 20W LEDs out there... there's a downside to all. This isn't even out yet so we don't even know it yet.

[xwingband]

Well, on a lark I checked mouser's LED collection... they have the atlas one. So I have one of these 250lm suckers coming. :)

[Jonitus]

$15.82 for 250 lumens of warm white goodness? You can't beat a deal like that.

lol for a second i got lumens and mA mixed up.

Is somethng like this available bright enough for a saber?

[Lord Maul]

yup, it's called a RGB led. 3 one watters on one mount. or you can wait for the Tri Lux to come out, that one holds three 3 watters :shock:

Don't pay attention to Maul... he didn't look at it enough. That's more like a decoration LED. Too dim.

Prolight makes some RGB's... a bunch of smaller companies too. Lamina included.

[Lord Maul]

but there are RGBs that you can use for sabers.
i didn't say you could use that one, just that there are some out there :roll:

Ok I think that's the Crux, the Lumens is the important stat correct? the LEDs from that page seemed to have really high levels, but maybe I'm missing something. a difference in how manufacturers calculate brightness maybe? like Hard drive manufacturers using metric calculations to get 200GB when computers use Binary to read the same disk as 170GB?

[xwingband]

Well, most small LEDs are measured in mcd (micro candelas). High brightness ones are in lumens.

There is a convertor online, but it admits it's rather limited and by no means exact. Usually you can look at the amperage draw too. Those are only 20mA. That's decoration LEDs, high brightness ones start to get in at like 350mA and up.
