Just asking for an estimated lead time from now. That's a kind offer, but I didn't mean to express any dissatisfaction.

no sorry, its bs to make you wait longer than you signed up for. I took all the engines down for now till i can get caught up. thursday is a big big day for me. sink or swim so to speak on things larger than cobkits. im feeling better now, almost 100%. non-custom orders are going out quickly again. if it would only stop snowing and once i get past thurs things will hopefully be back to "normal". I havent had the luxury recently of "let it snow ill stay home and work on leds" but i hope to have that option soon.

Can we get the engines un-assembled for a slightly lower price normally or is that a one time dealio for this dude?

That's still $30 saved for a 300W light! Thanks for the info my dude, defo going with some CXM22s to build up my new breeding facilities once I get the capital. Gonna be looking at two 4x4 spaces for breeding chambers. Probably two 16 module lights, 880 watts max each on 4 HLG-185h-48A drivers per fixture. I'd be looking at about $1470 after discount, right? Any further discount for an order of that size?if you priced out parts it would be ~$5 cheaper. $39.50 for chip+sink+holder. not getting rich on these

Hi @CobKits, my light engines arrived last week, and are running smoothly for a few days already. Thanks again!
Quick question - the dimmer on the power supply has 2 adjusters (labelled Vo adjust and Io adjust). Both of these affect the brightness so I'm a bit unsure how to use them. What is the difference between the two adjusters, and how should they be balanced?

You will need a multimeter cause u messed with the voltage adjustment but the lo adj is what you wanna use to dim them the lights. Lo adj affect amps

What watt driver you have?Max forward voltage for the cxm-22 is 55v but lets say 54v. If you are using hlg-185-48 then the max voltage on the driver is 53v. So you should be ok. But per the cxm-22 it has a 50v min so i wouldn't go lower then that.

ive looked just about everywhere. even direct from china after shipping and everything most places are within a few bucks of each other unless youre ordering a whole lot of them and picking up at the port. the only reason to go outside the box and order from a non sponsor is if they just dont have it or back ordered etc. i just looked at some of my save quotes from alibaba and the drivers were within $2-20 of what the vendors sell them for but after international shipping you are paying the same if not more on small orders.
i got a nice quote for heatsinks until i saw the shipping was $185 for 32 of them
which put them at the same exact price as most vendors.
