Newarks shipping prices were ridiculous when I tried to order some wago connectors. When I emailed them to ask if they would ship regular mail, or work with me for better shipping options they responded with "no"

I won't ever deal with newark again. Digikey treated me right and had me the parts I needed within days, sadly they didn't have the wago's but I found them elsewhere.

I agree there shipping to Canada is $25 and normally wouldn't deal with them but at this price might be worth it even with $25 shipping for some.

Depending on order cost I sometimes deal with Mouser because they ship free over $200 but again $20 shipping to Canada if you have to pay versus the $8.50 I believe Digikey offers. Digikey is priced a little higher then mouser for the most part and doesn't always have what I need (Meanwell Drivers for example) But I pretty well bounce my buisness between the two.

Thanks, CanadianONE. I happen to have some APC-35-500 drivers and heatsinks on the shelf so I'm in for some passive dual COB side bars, 17.5W to each 3000K CXA3050.

Free shipping to US if over $50.

Is this the graphic, Abiqua?

Some people might be disappointed--the Newark site does not update available inventory after an order is placed. I don't really care if my order is canceled; I need to stop hoarding COBs.

Yes that would be the right efficiency spreadsheet. I was wondering about the updating of the inventory. More then welcome to share some of your hoard with me @sanjuan lol

Looks like a good design. Personally not a fan of those heatsinks but that's a personal choice. To expensive when it came to getting them to Canada. Tried to find something in Country that wasn't outrageous but had no luck.

I don't like passive heatsinks. I've never been a fan of them in PC's and I won't be a fan of them for LED's either. If a cob fails and starts heating up without fans on those bars and you're in trouble, you could lose multiple cobs. There's a reason they don't just throw one massive passive heatsink on top of a PC motherboard. It's unsafe if your GPU get's too hot it could take out your CPU if that was the case for example. Each part should have their own heatsink so that if one part fails it doesn't cause a chain reaction of all your parts failing.

* for all the PC nerds I know there are a few boards out there with a massive heatsink on them, but they are few and far between. Those boards are not designed to have a long lifespan they are gaming products which are designed to have short life spans, as all gaming products are.

Personally would use Arctic 11 or arctic 64's or something similar. Might even be able to catch a deal ordering 8 at once. The CPU coolers are about 9.99 in Canada, or 5.99 in the USA depending where you're located.

Passive is safer than active. An active heatsink requires active cooling to remain within design tolerance, if a fan fails so may all of the cobs on the heatsink if they overheat. A COB cannot magically start producing more heat.

pretty sure I have seen cxa3070's in the 34 dollar range, but it would be great to see them for around 20 bucks
