I have 2 chips

50 volt chips running and parallel.
When a 65 phone no load on a 700 million amp 120watt. Driver. It is getting very very warm and it does not seem natural to me that it is getting so or when I had a mean well and invent Tronics running and neither of them are getting so hot

I am thinking the 3 amps max 100 watt 2.6 amps Max chips are just too much
For this 121 driver it is a name brand driver waterproof I don't understand why its having so many problems the driver in their picture is the driver I have problem is it is a mess label driver sold as a mess label driver it doesn't have the million page it says it has it only has 700 million send it only has 65 volt open I got it for $18

they should be run in series but the two cobs do not have enough Vf forward voltage 100v when the driver min is 103v. you need at least one more cob to have adequate Vf to run driver. as wired each cobs is getting 103v and 700mA current which would be 72w per cob or 144W total a lot of power being drawn for two led cobs.

Thanks for catching the 103vf minimum.

Driver is seriously miss labeled it is only a 53 volt driver or when I put them multimedia wanted in only gives me 64 volts the driver is Miss labeled I'll show youScreenshot_2017-07-01-05-46-10.png it not Screenshot_2017-07-01-05-46-10.png when you look at it it says 2100 milligram so want it but when you look at the million pitch in now put on the other side of the label it says 700 amps and it says it has a hundred and some bolts it does not hate was sold as a Miss label driver it has a forward voltage of 64 volts when on hooked up to a load without hooked up to load on multimeter says 64 volts how am I going to run them and series Warren 120 watt 64 volt driver when the chips are 50 volt teach that makes no sense no disrespect too I just don't think you're aware that the driver is severely miss labeled

Your electrician I hear so much about I think real styles 11 said that you know your s*** backwards and forwards I wish I knew a better way to Dimmitt my meanwhile 2:40 if you're with the better way to them them than tanchy please let me know

Anybody know anything about shrooms my brother heading some and he has blurry vision and it's been several days since he's taking them and colors are very vibrant to him when he goes outside any hair short term memory loss from the last time he has taking them he had taking too much evidently and he is having a bad reactionScreenshot_2017-07-01-00-27-51.png Screenshot_2017-06-25-18-25-29.png

If it is 64v only enough for one cob connected in parallel you will get 2100mA x 50v or 100w per cob for 200w max which is why your driver is very warm a lot of power thru two cobs maybe not designed for 2100mA current draw. I know cree has a cxb3590 that can draw that level but i drove them at 50w instead

That sucks I can't send you no voice recordings

The drivers only a 700 milliamp inch driver I will send you a picture of the chips I appreciate your help the driver has 120 wattsScreenshot_2017-06-23-06-54-09.png this. Chip 8 cash 3step chip 8cash lol i no 1step is bast

50v x 700mA = 35w. Should not be hot so you are drawing too much power in parallel mode it seems. at 64 volts you can only power one cob with that driver. seems more than just mislabeled as well, if volts are only 64, that is an odd number for a Constant current driver.

Output voltage range; 103-171. Your parallel wiring setup; 50v. 50 is less than the minimum output. You would have to wire them in series. Maybe even that would be too low, might actually need 3 if they draw less than 52v each.

Is there any writing on the back that may help point us towards it's actual part number? Is it possible it was dimmed from 103v by a previous owner? How did you obtain this mislabeled driver?

Ain't mislabeled. He just didn't wire it properly.

Read the thread buddy I'm sorry that you don't know but the driver is Miss label the driver only has 700 million page have you seen the label it says its a 2100 mah driver and then when you look next to the output it says 700 million pitch and then when you hook the multimeter up to it it only gives you 64 volts I called the eBay seller up he got pissed off at me for buying it and wanting to return it and I don't even want to put his name out there because I may have to buy from lol and only has a maximum of 64volts the driver is the most f***** up miss label soul driver a dude on ebay has a lot of these that are never used but are f****** miss label 20 box I paid made in Ireland it says

Here you go guy here's the driver but I don't know if there is a part number but guys its not the correct outputScreenshot_2017-07-01-05-46-10.png lxd120-2100 model number I figured Screenshot_2017-07-01-05-46-10.png

Oh, okay maybe it is mislabeled then. Don't buy cheapo drivers off eBay then I guess. Probably would have burned out in a few months anyway. Cheaping out on power supplies doesn't usually turn out well.

But you do realize that a power meter will only show the voltage that's actually being consumed by the LEDs, not the full output capability of the driver, right? And you're probably lucky it wasn't really 2100 ma because that's pretty high. I don't know what those COBs can take. 700 ma isn't bad actually. Anyway, I'll look into it a little more and see if I can find anything helpful.

1499022175063-652737356.jpg the gap that you see between the two checks for the for chips I should say there's a little bit of a gap I have been saving to either put a already made Chinese purple LED light between them for Cobbs or to put some color or on color quantum boards and place where the gaps or what's your opinions anybody got any cheap
