Thanks GG for the math.:) ( you write TIM ads .5 -1 to thermal resistant but from the math i think u meant .05 -.1 pleas correct me if im wrong) so if i understand than for cxb 3590cd with low quality TIM at 49w the math wold be; 49(w) x .44(heat w) x .69(thermal resistent 0.59+0.1 for the...

Is it true that if a sink have the thermal resistant of 0.59 c/w and you mount a chip at 49w 56% efficient which means 21.56w of heat,the temp rise above ambient will be 21.56 x 0.59 =12.72 celsius above ambient temp? Is this theoretically correct? Without considering many variables like TIM...

hi mark,what is the weight of the sink pleas?(sink only)

thanks for this man^^^^^^:smile: i wold listen to them to,and for shure easier to clean the sink than the cob as @Isawthelight mentioned :hump:

What abute the corrosive reaction betwen grafit and alominum ? SDS mentioned this feu times before. Maybe better with graft on cob side,and sticker on the sink? What do u think guys? idd like to use them myself....

i think being safe is a good reason to sand the 5x5 mm connection point of the anodized finish,but thats only me:peace::bigjoint: i do agree about the washer thou . :hump:

there u go:smile: http://www.amazon.com/Wago-222-415-LEVER-NUTS-Conductor-Connectors/dp/B01AO24OQY/ref=sr_1_2?ie=UTF8&qid=1454537856&sr=8-2&keywords=wago+connectors You are right about the driver,sins it is anodized,it dose not conduct (or less conductive) this is why u should ground the...

thats the way to do it:smile: i use the 2 way for dc side connection and 5 way to connect 4 light bars to one plug:hump: welcome and pleas do,its much safer:smile:

yep..the real way and very simple:D its not grounded twice its the same ,one ground the driver(metal frame)and the other the sink,grounding is only for bare metal parts,if u had a plastic sink it wouldn't be needed because its nod conductive :bigjoint:

from the hlg ac side u need to connect the ground wire to the plug and also a wire that goes to the sink and connect to it,using a screw and a ring like this kind ...

Hi,how do u ground elg?sins it doesn't have a grounding on the ac side,it's only live and natural. Can u get the grounding frome the wall plug?I think u can...have u done it already ? Can u post a picture pleas? thanks buddy :smile:

i think u could run 7 3590s on the hlg 240h-c1050 :bigjoint: https://docs.google.com/spreadsheets/d/1nKfc12OCuDu7puJCa_6maefyCVm3gS5sBmzAXOlh06w/edit?pref=2&pli=1#gid=1157681753

yes,meanwell hlg-320h-c,still under development. 320 watt cc driver. http://www.meanwell.com/catalog/led/#p=35

i also got my package of 10X elg-150-c1050A from jerry today,the invoice on the package said 28$ :clap::clap::clap:,jerry is the man:bigjoint:. the only problem with the elg A is that the built in dimer is on the bottom of the driver,where the wall wold be . (i don't know what they where...

ok thanks,ill try to get some prices and post it for u guys ,i got my mw already :bigjoint:

They look like good drivers ,i couldn't find the price on the sites that sells them,without a quotation that is. Do you have an idea abut prices for the 150,200,240 w ,cc ? :D

hi robin,or A.P If it's not a big trouble ,can u show a picture or the 3590s measuring point,i didn't get where exactly is it. thanks allot edit:oops,sorry i find it,i didn't notice as it's so small :wall:

yes 5mm length is ok,i wold go a little longer, if your sink base is 6-7mm i wold go all the way,i wouldn't use this drill-tap combo,idd use a drill and hand tap (with a handle ) separately unles you got the pole drill or taping machine :peace:(remember to use tapping oil for drill and...

correct me if im wrong ,airwalker,i thought u meant somthing like this http://www.amazon.com/Greenlee-DTAP6-32-Combination-Drill-6-32NC/dp/B001B1AP6G/ref=sr_1_7?ie=UTF8&qid=1453573235&sr=8-7&keywords=drill+tap

u could i gees ,never used one of those, seems hard to control,u will need a drill with slow speed and sensitive clutch not to brake the tap in the hole .idd go with a drill and a tap or self tapping screws for metal,there are to kinds,one that cuts the grooves and one that just press the metal...
