HLG 550 vs Going DIY

Recommended Posts

Could you maybe list every component that your build consists or maybe a link to a thread that does?
I need to try and get a better understanding of the components and what they cost individually. As mentioned I know very little about LED's so when you guys start talking QB76464 and LM76587 diodes I haven't the faintest clue what you're on about 
Basically what I know right now is that you need a driver, lights and heatsink
Are meiju reputed? 
What happens if a diode or two goes, what kinda replacement costs are we looking at?
 
So an LED build generally consists of the LED's (in this case, strips or quantum boards.... I vote quantum boards), heatsinks / cooling and a driver.
Then wires to wire it all up and that's really it.

When it comes to LED's, they're not all the same. The actual LED diode itself makes all the difference.

In terms of costs if a diodes die, pretty cheap. You'll probably pay more on shipping.
I haven't actually tried to source the individual diodes locally but I'm sure one could get then without too much fuss.
In terms of replacing the actual diode, if you can solder and you're comfortable with SMD then it won't be difficult at all.

Here are some very good guides which provide theory and such : https://ledgardener.com/diy-guides/

I don't know hey.... 

I like to think of myself as a pretty good solder, but those solder points are just so fine, you would need a pretty fancy iron and a very pointy tip. 

And the way the boards are designed makes it hard for single diodes to go... Diodes are pretty specific and if they work once, chances are that they will work the remainder of their lifespan without issue...even longer if you don't run them at max the whole time. 

I am actually trying to think of someone who has had a few diodes go... And I really cant think of anyone.

There is no chance you will fix the SMD on the quantum boards with a a plane old soldering iron lol. Go and buy a practice SMD board you will see how difficult and painful it is.

Oh yeah, not with those shitty R99 irons.

Preferably a reflow and soldering workstation.

 

I also don't think it's likely a diode or two will die, but it's always possible.

Have not fully considered other options so more than willing to consider other brands, provided they have a good backing.

 

I think a look at atreumlighting.com is well worth it. I have 4 ARA-20 strips and they great I can only imagine what 6 ara-40's on a 600w driver will do. 

 

Also have a look at the review from MIGROW https://youtu.be/q20WS9qtL00

Yes, we swap out the whole board when something goes wrong

Definitely recommend the led strip builds. https://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/
Meanwell also have cheaper drivers now with the elg range.
If you go with digikey, shipping is free from the states. 
I also watched growmou5's videos on YouTube for like 6 months over and over before I settled on going with leds.
Keep in mind that you still pay for customs.

I personally prefer QB's over strips, but both can work great. It comes down to the LED's and the way you layout the lights.
