Hi all, browsing an infamous asian online marketplace I came across driverless cob that you plug in the wall directly. Obviously with some sort of heatsink.
has anyone ever tried them with MJ?
I ordered one jsut to get a sens of how they work. Will let you know when I'll receive it.
Having said this, as I have extremely limited space to grow, I will definitely not use it on my girls for the time being.
the image shows the spec from the site. should you want the link let me know. I don't like to do advertisement.
Yes I have seen many of them from different vendors, brands and color temps on eBay and they are super cheap. The electronics are on board the COB chip to achieve the higher voltages. I actually ordered two 50w 2700-3200 COBS for $4.11. Well, I ordered them over a month ago lol, and still haven't received them. I'm not worried, my expectations are low, if they actually ever come. I just want to tinker with stuff.
The ones I ordered are advertised at about 100lm's/w and it does state they should last 50k hours. Again, my expectations are lower than that. I mean they are like 2 dollars and a nickel a piece. To think they would "out shine", these reputable companies geared toward top quality and efficiency is just silly. No pun intended.
Anyway, haven't received them yet. I'll report back when I do and get one up and running. Tho, my experience will be basic sense I have no meters to test with tho, I may throw a few things together and use my electric meter to get a power draw reading from the wall. If it actually works. I do not plan on growing with them anytime soon.
If they don't work, I'll report back they don't work and just throw them away. Just thought I would chime in tho, I really have little to add except I have ordered them and the cost. And the long long shipping time from china to the USA.
P.S. I vaguely remember an eBay seller with the moniker or brand mazer? I don't remember for sure though.
