LCC Vs. LOC?

[Benm]

I personally like the LCC because you get a 2 for 1 deal with the GGW sled. Also because it is closed can there is less chance of physical damage during the

I'm a bit divided on that: Surely the case offers the LCC protection, but its also much harder to extract from its sled, increasing the chances of damaging it in the process.

Personally i consider the LOC to be the red workhorse. Its slightly cheaper, easily extracted, and so far proven quite reliable despite the lack of a can. On a next projector i'd consider twin-LOC for the red part, provided nothing better comes along.

Thanks Man! I need a LCC graph. Imma Look, but if you find one first lemme know.

I think that this is the last time I'm going to say this . . . .

There is no appreciable/practical difference between the LOC and the LCC. There is more diode-to-diode variation in each type than there is between the average output of the two types.

You can use the LOC "graph" to decide the current for the LCC.

^^ agrees with that. If it were the exact same chip shipped with and without a can, it would be impossible to tell them apart based on performance.

whoa... deja vu!

Triple Glitch. Didn't mean to irk anyone (Dave). I figured there was a LCC graph and was going to look at them if they were available. No problem.

Problem solved. Thanks everyone!

If you decide to go with a GGW sled, check with some member's here on the forum. I'm pretty sure there are a couple member's who are selling them cheaper than you can find at the websites. :beer:

Im not sure I would agree with that..

I have had LCC LD's burn out at less than 200mW after 10mins constant on..
The LOC seems to be more reliable at higher currents IMO.

Also, if you make say a pen using 2 x AAA and a cap, no resistor, the LCC
will give more mW than a LOC.

A LOC with 2 x AAA will give less than 200mW where the LCC will go 225-230mW.

There are advantages and disadvantages depending on what you use them for.
The differences are minor, but id go for a LOC any day as I dont like how easy the
LCC go LED..

Thanks! Will probably get one from Modwerx. Seems cheaperest.

YMMV. I have better than 40 modules out there running the LCC at 420mA (Rkcstr or Flexdrive). I also made more than a few lasers with these. They produce just under 250mW after acrylic lens. My personal LCC is running at 500mA. It is producing >300mW after 650-G-1 lens. IgorT is running one at 510mA. I am "kind" to my hand helds. IgorT is not :eg:

AFAIK the majority (if not all) are being used in hand held lasers. I do not know if any of them are being used in a projector.

This was the majority of use for the ones I had, IIRC I made approx 25-30
in handhelds and was disappointed in the longevity in labby's..

I was going to use a couple in an array, by the time I got the beams aligned,
one popped and soon after the next.

I replaced them with LOC's and have not had a problem since.

At one point I had at least 50 of the LCC's from different batches of 6x GGW sleds.

I have run them as high as 550-600mA in a handheld but they didnt last long.
