rosswaa Posted March 29, 2015 Author Share Posted March 29, 2015 Waiting on the vero 2's, been told a few weeks till they're out so no point rushing for them. Nice one mate would appreciate it Link to comment Share on other sites More sharing options...
Badders Posted March 29, 2015 Share Posted March 29, 2015 is the datasheet on the bridgelux website for the current series on the new series? also philips have announced some big reveal on the 15th april for their new cob, quite interested to see what they have come up with, there last installment was early 2014.. What are your thoughts on the CXB range? any reason you decided vero? Link to comment Share on other sites More sharing options...
Superdedupity Posted March 29, 2015 Share Posted March 29, 2015 (edited) Tried to PM you, will do as soon as you can accept. The subject of chlorophyll absorption is a prickly one, you try telling someone who uses HID about spectral dis. graphs hahahaha - ( l nearly broke the forum a few weeks ago, people were pretty mad at me for making suggestions against the opinion of the vanguard; witch hunt springs to mind) Anyway, I digress. No witch hunt, people calling you out on bullshit which you couldn't substantiate Start of it: http://www.uk420.com/boards/index.php?showtopic=354990&page=9 And it kept going: http://www.uk420.com/boards/index.php?showtopic=355082 No witch hunt, just you not accepting that you're bigging a product, without having any to reference it to; sure you claim to have never grown Edited March 29, 2015 by Superdedupity 1 Link to comment Share on other sites More sharing options...
~Sanctuary~ Posted March 29, 2015 Share Posted March 29, 2015 Badders still talking bollocks, what a surprise, why don't you stick to the other forum you keep harping on about ffs. 2 Link to comment Share on other sites More sharing options...
rosswaa Posted March 30, 2015 Author Share Posted March 30, 2015 Nah not found the second series sheets yet all I know is a 5-10% efficiency increase, should be interesting to see what Phillips have coming then but would have to be something special Cxbs should be really good if the cxas are anything to go by, only going with the veros on price point and they have awesome things being said about them.

Badders Posted March 30, 2015 Share Posted March 30, 2015 (edited) Yea the CXB datsheets look great, as you point out, a plus being the lower Vf for same drive current compared to the CXA's. I've done a few (basic) sums on the sizing of semi passive heatsinks so I'll post that up with a price later and a link, (just waiting on price and some calculation confirmation...). I'd hate to see a burnt out cxb 3070 because my shitty 5V adapter died my plan know is to run 100W light in my 47 x 45cm box. (~ 40W per sq foot) I'm gonna make that up with 4 x 700mA cxb 3070 or vero_2/29. I can't really decide, cree have better eff when driven softer, brigelux have more individual emitters in there cob so each junction has a propotionally smaller amount of heat to dissipate. They're also a doodle to fit. hmm... I'm pretty satisfied atm with 2x vero 29's @ 1.4A & 1.2A. I just wanna stick more cobs down haha Edited March 30, 2015 by Badders Link to comment Share on other sites More sharing options...
Badders Posted March 30, 2015 Share Posted March 30, 2015 (edited) + the drivers come at, 80 W / 100W / 120W / 150W = ding ding. winner. Edited March 30, 2015 by Badders Link to comment Share on other sites More sharing options...
rosswaa Posted March 30, 2015 Author Share Posted March 30, 2015 Not to shabby, what sort of price would a pair of 80ws be? I'll take a proper look when I'm not working but I'm thinking 2 vero_2 29s at 1400, could just go to town and run them at 3.1 and get some liquid coolers Link to comment Share on other sites More sharing options...

olesmokie Posted March 31, 2015 Share Posted March 31, 2015 hey guys, I've also been looking for some reliable drivers which don't cost the earth. @@Badders I'll be interested on how you get on with LSD, but i' guessing you could be up for a trippie {GROAN} email exchange... enough with the puns. I've been looking on fleebay and came across these The 600mA is £4.95, 900mA is £8.45 and the 1.5A is £11.95. I was just about to order 3 x 1.5a was wondering if anyone has had any experience of these cheep drivers. Indecently if you search for Waterprood Led driver transformer power supply 48v not much else comes up. I might get some see how they are...

rosswaa Posted March 31, 2015 Author Share Posted March 31, 2015 The only thing iv seen about the cheap drivers is they won't power a vero, but will a cxa as its out of vf and the veros are more picky. But that could be wrong. Iv not seen anyone actually trying Iv been busy with my chameleon as the marine shop messed up the water and he's now in a bad way but I'm getting round to taking a peek at some other possibilities Link to comment Share on other sites More sharing options...
Badders Posted March 31, 2015 Share Posted March 31, 2015 (edited) @@olesmokie - I just had a fast tech driver die on me, cost £10 for 1A (measured @ 750mA) - If I were you, I would shell out a bit extra and get a meanwell or recom, typically they will have PF correction and be >90% efficient. + dimmable if you pay a little more. For 1 cob have a look at the mean lpc 60 1400. good starter until you get the bug Whats your total power alllowance? @@rosswaa, its the Vf (forward voltage) of the COB that determines whether a driver will power it or not, e.g Vero 29 @ 700mA - 37V cree cxa3070 @ 700mA 36V v29@2000mA ~ 40V (off top of my head, datasheets are there if you want accurate ) IF you get a driver with a Vo of say 75V that could just run 2 V29's@ 700mA (37*2=74V) but it wouldn't drive 2 V29's@ 2000mA. (2*40=80V) (it might drive it but not at the rated current) Hope that makes sense. B Edited March 31, 2015 by Badders Link to comment Share on other sites More sharing options...
olesmokie Posted March 31, 2015 Share Posted March 31, 2015 @@Badders total power 150w, 3 x 50w. 3x cxa3070 AB running at 1.4A. Mouser have them for £13.32 each and if I get 4 I'll get free deliver but they won't have stock until 6/4/2015. Which I guess isn't that long now. I have thought about running 2 cobs of one driver and one of another but haven't found any with either enough power or voltage depending on parallel or series wiring. Do you know of any? Do you have reliable suppliers in the UK who are reasonably priced? Cheer. Ole Link to comment Share on other sites More sharing options...
