12x BR DIODES
 
All 12x Owners

Last Update: 2011-01-17
Previous Update: 2010-11-09

NOTE: To facilitate the readers, the last updated text will be written in red color.

Well, the 2010 starts with the increase of 12x owners. Due to this reason (and following some LPF members suggestion) hence the decision to start a new thread for the "12x" BR Owners data collection, to open for them a dedicated space also in view of future 12x diodes improvements.

So, hereunder are the datasheets of all the 12x Owners, further updates will be implemented here.

12X DIODES BENCH TESTED


As some members have started to test 12x diodes on bench, that is differently assembled than in a host, with the scope to push diodes beyond the limits imposed by the use of hosts/batteries, hence the decision to create a dedicate datasheet/plots chart, as shown herebelow:

Very cool. Im obtaining abit more money, and once my Sf-Aw is sold, I will purchase a 12x. Just to be sure, this is the proper driver for a 12x correct? Amazon.com: Pioneer BDR-205 - Disk drive - BD-RE - 12x/2x/8x - Serial ATA - internal - 5.25": Electronics

That is the correct drive. However, you can get them on eBay now for ~$205 shipped.

Peace,

Alright sweet. Thanks for the info. Those 205$ ones are new correct?

Yes. They are new. Just search "BDR-205" As with all eBay sources, you will find different prices.

Peace,
dave

If anyone orders the 205 drive, I will purchase the small 3.5mm red diode from that drive if you don't nee it, send me a pm if you're looking to sell it.

Re: 12x BR DIODES
 
Just curious. Does the drive need to be purchased because the diodes aren't available anywhere, or is it because something else is required from the drive besides the diode? Thanks

Re: 12x BR DIODES
 
Yea, they aren't available.
Well, they are, but are you willing to shell out >$1000 a piece?

I gotcha. :)

FrancoRob;

Here is a graph from Nichia on their 320mw 12X Blu-Ray diode.
http://techon.nikkeibp.co.jp/article...34787/fig6.jpg
They state 260ma for 320mw ...
And we know their instrumentation is accurate.

When I drew their graph in your chart, it overlapped with the Quisp datapoint.

Larry:

Well, taking into account Nichia plots, just to make some simple valuations, Nichia mW/mA ratio is 1.23, while Quisp ratio is 1.29, so il looks that his diode "relevant efficiency" is better. The current values in comparison (260mA and 360mA) give a 38.4% of current increase, against a P.O. (320mW and 465mW) increase of 45.3 %.

Taking care of GoldenDragon data, the "relevant efficiency" mW/mA ratio is 1.49, while current (260mA and 300mA) and P.O. comparison (320mW and 448mW) values (always with Nichia) show respectively a Current increase of 15.3% against a P.O. increase of 40%! :thinking:

Obviously two points only do not allow to take any statistic :undecided:: BTW, I'm anxious to know Igor 12x murder test results..... for life valuation too....

Re: 12x BR DIODES
 
FrancoRob;

You are getting different slopes than I did.

The threshold current must be subtracted from the current reading to get the slopes reported in the diode data sheets. I estimated the threshold currents to be the same.

I took (Power out / Current In - Threshold Current).

I got 1.42 mw/ma for the Nichia.

I got 1.43 mw/ma for the Quisp diode.

That is only a 0.7% difference.

I can't wait any longer --- I just ordered a BDR-205 for $203.
I need a new toy.

You "kids" have been testing long enough :undecided: Now this old fart has to play with one. My last 8x diode has fired me up. :beer:

I know how you feel. I have one here in a baggy . . . . taunting me.
