Laser fire sale Large images PRICE DROP

[kiyoukan]

Looking to sell my old stock of laser items.
Shipping within USA is 3$, INT 10$

cr123a battery chargers comes with 4 battery's.
(12.5$) (over 40 in stock)

Silver host
takes 2 cr123a (10$) (over 20 in stock)

Here is an example of it with a HS and diode

Black host
takes 2 cr123a (15$) (over 20 in stock)

Heatsinks for the above hosts are available separately.
Black host heatsinks 15$
Picture of heatsink for the black host

Silver host heatsinks 10$

Re: Laser fire sale Large images

I'll take 2x Black laser host takes 2 cr123a (25$)

And could you PM me about the ST-drives.

Cheers!

Re: Laser fire sale Large images

I am interested for the diodes and the batteries !
Very nice deals man !
Whats the problem with the drivers ?

Re: Laser fire sale Large images

I think I'd be up for buying the 1085s. Can you tell me the complete part number of the version those are?

Re: Laser fire sale Large images

Pretty sure it is LD1085CDT-R

Re: Laser fire sale Large images

What type of projector are the 445s from? Are they from an M140 or A140?

Doesn't really matter at 35$ a diode :eg:

Re: Laser fire sale Large images

Does to me If they are M140s, the deal is good enough to buy some of them even though I don't need them now. =p

Re: Laser fire sale Large images

Does that black host come with a heatsink or is the one in the photo just an example?

Anyone know if you can run one of those diodes at ~300mW w/ unlimited (or very long) duty cycle? I'd be interested in some then.

What am I missing - aren't these normal 445s?

Why are duty cycle considerations any different for these?

Re: Laser fire sale Large images

You're not missing anything, RHD, I am! Which is why I was asking, haha. I know the upper end duty cycle limits but have never seen the lower end, basically I was asking what the Ith (threshold current) is for these and the approximate duty cycle at just above threshold. No one ever seems to care about low power builds so the info is a bit harder to find.

Oh, gotcha! You were asking just in general with 445s.

You can do some of the math to get a sense:

- Say 450mA in for 300mW out (it's probably less efficient in the low range)
- That's (450 * 4.5) = 2025mW in.
- That's 2025 - 300 = 1725 mW to dissipate through a heatsink

Now, you could do some funky heatsink math, or you could just find an analogous diode. I think the Mitsubishi 635 is an excellent comparison:

- Say 1000mA in for 700mW out.
- That's (1000 * 2.5) = 2500mW in.
- That's 2500 - 700 = 1800 mW to dissipate through a heatsink

So, you basically have similar heatsink requirements to a Mitsubishi run at 1A.

Re: Laser fire sale Large images

I want to know aswell if they are M140.

Thanks.

Aha! Thank you very much, RHD! Yeah, funky heatsink math ftl.

Re: Laser fire sale Large images

The diodes are A140 diodes.
If any one wants the whole projector i am willing to let it go for 720$.
That brings the price down 30$ a diode if you buy the whole thing plus you get all the fun goodies of a projector.
