I need some help with DIY LEDs

Hoping someone can help me troubleshoot a DIY LED issue. I am using This driver.

https://www.rapidled.com/mean-well-hlg-240h-c1400b/

Which states that it can handle 29-59 LEDs ang 179 volts. 

I am running 27 blues at 3.4 vlts=91.8vlts

And also running 16 whites at 2.8 vlts=44.8

Totaling=136.6 volts

 

The problem I keep having, is that an led blows after several hours of use. The leds are wired in parallel as demonstrated in this video below.

I have set up many of the projects with the smaller drivers and never had any problems. This is my first time using the driver designed for high quantities of LEDs.

Are they wired in parallel or in series? Normally leds are wired up in series, and that's the only way you can add them up like you are doing. 

 

I am not familiar with this driver, but you should make sure you have enough leds in the series string to meet the minimum voltage. I assume the driver can internally limit the current? If it is just driving 1400mA through them, that may be why you are popping them. My experience says that is too high a current for most high output leds.

 

What leds are you using? Most should be limited to 1000mA.

I did say in parallel, but I meant in series as in the video. I'm  sorry but I am a dummy when I comes to electronics. I am using these two LEDs

These LEDs are limited to 1000mA. So does that mean if the driver has a max output of 1400mA it could blow the LEDs?  Is there a way to fix this?

It won't drop the current, if that's what you're asking. It will increase the voltage though. Do you not have a dimmer? Rapid should sell one.

No I do t have a dimmer. Rapid does sell them and I will go that route. Thanks for your help.
