LED group buy - Ends December 10th - WICKED DEALS

[Milad]

Nice, i just saw you got the T6s. You gota flaunt those around and get them in a build thread with some pics as soon as you get them. I think there is only a hand full of people that have the T6s and even less in Canada.

ya shipping sucks. USPS has flat rate boxes that allow me to stuff as much as I can in the box not worrying about weight. So 4 LEDs is same as bricks.

im trying to find ways to make the shipping cheaper but still cover everyones butt.

SEE THE RESULTS I POSTED ON THE NEXT PAGE.

Has any of you guys that bought led threw this post tested them yet.
Reason for asking
i just tested the XPG and XPE with a puckpuck 24VDC 1Amps maximum drive.
Running the XPG cool white have no problem at all.
Running the XPE royal blue well they keep on burning,but if i test them at a 700Ma no problem.
To my understanding XPE could run at 1000Ma without burning.
yes the heatsink temp is at 25 degree.
yes i placed 6 led in a series for the buckpuks.
and yes i do have a test meter.

This reply is not intended for bad thread.i just need to know because i was planning to place an order for the drivers tomorrow(it does make a big difference if XPE royal blue will not run at 1000Ma.

thanks

Although the XPE's are "able" to run at 1000mA...I don't if anyone recommends it. I would try to stay around the 800mA range to prolong life and wear.

[Milad]

how long are they staying on? it should run at 1000mA
Ive only tested mine with 2 AA batteries in series atm since im still playing with the design.

which power supply and buckpuck are you using?

[eli@fijireefrock.com]

they are staying on for no more than 10 seconds.
i would like to run them at wat their max should be because i have no problem keeping the temperature near 27 degree.
power supply i used on an old led setup 24VDC 6.5 Amps
dimmable 24VDC 1000Ma buckpuck. cant recall the model but i used it on my old system running it at 1000Ma for phillips 3w led and no problem.

Now everyone is going to be scared to run theirs at 1000mA to check it out! Well I don't think any other LED looks like the XP-E expect the XP-G and the XP-C. The XP-G only comes in white, the XP-C does come in royal blue but they would burn at 700mA. So I don't think they mixed up the LEDs (hopefully). How are you measuring your current?

Mine are running perfect - all 20 of them! And the light they throw off is amazing. I replaced a 250 W MH (on a 50 gallon 36" long tank) with 30 LEDs and I think I have more light now than i did before!

Actually I'm still looking for a good driver for them. I'm looking for a driver that can power them to their full potential in a strip by themselves. I'm going to light my frag tank with them and supplement actinic with T5's (or possibly get some more royal blues, haven't made up my mind yet). So I'm looking for a good driver than can take advantage of the full 3A potential, run only the four of them in a strip and is dimmable. Any ideas?

[eli@fijireefrock.com]

try these guys i like their drivers.prices are decent.
very helpfull ask for Greg
go to the led driver section and pick the you need.
i like these drivers,you dont need resistors and run them in series.

They look like they have a lot of options but, forgive me, I'm not technically inclined enough to know which is the right one for me. I was hoping to find something a little more "plug and play" than those!
