i'm thinking about using these for my vero 18 lights. any thoughts on them or should i bypass them? i haven't soldered in years and not sure i should with my shaky hands.

do it they look good
but read the data sheet carefully, i believe they have a voltage limit

You can use up to 5 Vero 18 gen6 in series while staying in spec. Voltage to ground for Vero gen6 is less than the max voltage of a Wago-222 (400v max) so they can handle whatever the Veros can handle. The Pico-EZmate has a max voltage of 300v, also greater than the max voltage for Vero gen6, so you can do the whole project without soldering if you choose.

If you wire them like they are intended (series) its not THAT hard to go over 300v. More to do with your driver than the COBs youre using...
So in other words, we need to know what driver you plan on using before giving you a definitive answer...

Cobs have a "contact to contact" voltage rating so in series each brand/model of chip will have a limit on how many should be used to stay within the manufacturers operating limits. Gen6 Veros have a 150v limit and gen7 have a 500v limit. Specifications for gen6 don't allow for more than 5 Vero18s in series.
Vero18 gen7 D will allow about 15 in series. That will place the weak link at standard 300v wire and the Pico connectors. High voltage wire and soldering the contact points will allow a circuit voltage up to 500, 400 if using Wagos.

I see, useful information. Where did you find that info? I feel like Ive gone over just about every data sheet available on the Vero's and dont recall ever seeing anything referencing that.

do you mean "contact to ground"? 500V seems really high for a contact to contact rating on a single chip

vero 18 bxrc-35e4000-f-23, lpc-60-1400 on a alpine 11 plus cooler. digikey has the ezmates and i thought i would order two more cobs and grab the ezmates as well. thinking 18 gauge wire same as my drivers.

i kinda skipped through the thread and from what i see i should be ok. thanks folks.

I get a diffrent voltage rating from the datasheet on digikeys: it states max voltage 130. Can anyone advice on how to get the 300v rated connectors or how to make sure im safe with the following setups? :
2 vero 29 gen7 version C on pairui lgsu250 1400ma (max rated voltage 189)
3 vero 29 gen7 version C on hlg240c1050 (max voltage 238v)
Or do i need to solder? Id really like to avoid it, but i know sooner or later id have to get my feet wet on the soldering.

So...
Completley unsafe? Or safe to try for 5 mins? Id really like to atleast be able to try i out but not sure now

I used to work for Molex, over 8 years in fact until relocating out-of-state. I made slightly larger connectors though, for automobiles.
Sorry, nothing substantive to add to the discussion, I just saw Molex in the title, lol.

I think the pigtails are 300v. If the connector is 130v max, it's sitting on top of the cob so max voltage may not take into account the additional insulation... or maybe it does. If it's been working that long I wouldn't be concerned.
