Yes reliability does vary. Over the years there has been an un acceptable failure rate from the bare 900mA Fasttech drivers. The OS brand 1.4A drivers also. On the other hand I have not seen any failures from the JHX model 800mA drivers or 1.4A drivers. The one I linked is similar to the JHX. I don't expect any trouble from them but not enough of them in use to say for sure.

JHX & DTF? sorry not familiar with these terms. Can you enlighten me please.

It's the brand names of the better eBay drivers. JHX 50w are not available anymore that I know of though.

I have never had an issue with any JHX 50w or 30w drivers. Hot to the touch...but no issues. Out of ~50 50w'ers and 16 30w'ers.

Edit: the 50w were consistently putting out 1430-1450ma for me

As I see it, little reason to choose LPC -150 over ELG, both are for 230V, but ELG if more efficient, dimmable, and are really close pricewise.

No more reason to buy hlg 120h if on 230V either imo.

LPC-150-1400 would work for three COB's if you are running 230VAC Otherwise you can go with HLG-120H-C1400 for three or HLG-185H-C1400 for four with dimming and great driver efficiency @ 115VAC input.

I found some CXA3590's for about $4 less than the cheapest CXB3070's. Any pros to getting the CXA3590s over the CXB3070's? Thanks all.

@EfficientWatt Does the ELG work in the USA?

Both ELG & LPC will work in USA but not on 115V regular outlet only on 230V double pole breaker. The downside to the CXA is slightly higher voltage and lower efficiency. Which puts you a little over the maximum driver voltage for both meanwell HLG-120H-C1400 (3 COB's) and HLG-185H-C1400 (4 COB's) Not to say they still wouldn't run them but they may derate the amperage a little to do so (Just theory never tested) Also attached a zip file with a few meanwell datasheets as options for your setup depending on which route you choose in the end.

ok so I just ordered 4 Vero 18s, 2 3000k and 2 4000k both 80cri. Now I want to get the most I can from them and I know the nominal mah is 1050 and 2100 being the max and the MW HLG-185H-C1050A could power them with room to add 2 more cobs in the future. The problem is that I may not be able to add any others and want to get the most I can out of the 4 I will have. I'm also looking to light a 2x2.5 ft area and at 1050 I would only be getting 24w a sqft.

So besides being less efficient is there any real reason I shouldn't get the HLG-185H-C1400A and get just over 160w of total power out the these 4 cobs and give myself roughly 32w a sqft. Yes I know with cobs its best to run them at lower mah but with my current situation and the cost of the chips and drivers thats not really an option for me at this time. Im already pushing my budget with the 4 cobs, the driver, the heatsinks and other building supplies,so the other 2 cobs aren't an option but getting roughly 40w extra out of the driver for the same price as the 1050 is my best bet. I also know that the extra power does produce extra lumens so its not just wasted energy, its just not as efficient lm/w as the lower mah. I also know that they can handle up to 2100 mah so the 1400 shouldn't be an issue so I should be fine with the 1400 right?

You loose about 2% efficiency but you gain in your total wattage and par watt's sq/ft also. If you can't spring for more COB's and run them soft I think you could go the HLG-185C-1400 route and still be able to dim down to 700ma if you wanted. Only other downfall about going with that driver you will not be able to add anymore COB's to it later as you will be running @ approximately 84% of maximum voltage of that driver and adding another COB just puts it over. If you could just spring for 1 more V18 it would put you get you up to your 30w/ft2. 5 @ 1050ma would get you up to almost 153 watts.

I think this is my final question as I have most of my parts selected. What are the difference between the CXB3070 AB and AD. I found some AD's for a bit cheaper than mouser. Also does mouser ever do sales/coupon codes? There is a holiday coming up 2 Mondays from now, and was wondering if it is worth waiting. Thanks all and especially @CanadianONE for the help.

The AD's are a higher bin and put out about 4% more photons at the same current.

Go with the AD's if you can. @Abiqua gave you the reason for me saying this.

Some other 50W driver options, not Mean Well but cheaper and may actually perform better (higher efficiency and power factor corrected)

I am actually using 2x of these to run a pair of Vero 29s. So far so good after 1 grow. They warm up a bit but thats expected. Build quality is kinda meh compared to Mean Well but as long as they function I don't give a shit.
