Hello Hybrid, I actually bought one of these (Panda from China) to do a head-to-head comparison. My belief is they are Epiled's. They are "ok", but are outright lyin' on their wattage (which I have found to be typical for the Chinese vendors, not all but 90%).. I asked the guy repeatedly...

Current across each when measured in parallel config is .89 amps per. COB (pretty much what Supra said :oops:) These will get me started, and that's excellent data for future ID of the correct meanwell. I will measure the current again when I run them long enough to stabilize at running temp...

Robinn, I haven't measured the current in parallel but now I'm curious. I'll do that and post first thing tomorrow just for the data point. You sure can tell which Chinese vendors want return business vs. those that just want that one sale...these were packed really poorly and I am even...

Thanks all! I tried to order a MW LPF-90D-48 from TRC but they told me next day they did NOT have the stock they said, would be three weeks so I cancelled. Yep they're cheapo's...but I can get three of 'em for 45 bucks (PLUS the guy includes a Chinese 100 watt COB per supply). I did it because...

Forgot to add the pic showing my fans mounted, and the suspension chains....

Hello Rollitup guys and gals! WOW I have learned a lot here from reading a ton of the DIY threads and I want to start by saying how much I appreciate this forum. I even got some advice here a couple months ago on another thread before I commenced ordering parts. It was a close contest between...

I've ordered some Vero29's in three flavors...doesn't look like there are any Inventronics 320's available at the moment, so I'm fishing around online for something that will power pairs of them; and build them into pairs for better positioning/penetration capability. Alesh, above you have...

Good info, thanks all! Alesh - that's an excellent plethora of solid choices. I had considered going with something similar to "(12)Vero13 + HLG-185H-C500" as the price point on them is dropping and I know they could do well in higher numbers. It just seems simpler for my first build to use...

I should have added, that I am going to build a dual 5K for veg (or higher K-value if I can...I think that was the highest I saw from the Vero). But the same supply would need to work there also. Rahz, was your calculation based on the 5x8 or the original 10x8? Not at all questioning the...

So, there are a lot of choices for the MW supplies...I am preparing my "build of manufacture" list and want to be able to run one supply for every two cobs, and run three different cob values (3K, 3.5k and 4K) so I can play around with the K-index to see if it makes a difference (unless this is...

Arrrighty, just wanted to give you an update and let you know I didn't "disappear" (not altogether anyway). First thanks to all who gave feedback on my questions/scenario. My plan going forward is: 1. Build a partition in the flower room and cut the room size to 5x8 with the option to remove...

Thanks for the replies everyone! It seems the more I look at the budget and the space I have - the more options I have to consider with less n less money LOL. So I am certainly taking all your feedback to heart and looking at: Combination of HPS and LED, build some/buy some cheaper Chinese...

@Dandy (and Getgr...) thanks I'll go look at the Vero's. Looks like several people on here have built with them and have good results. As I said, I may have to scale back the size of my room with a simple "for-now" divider as I want to keep my PAR/w high.

@GetGrowing...thanks I appreciate the insight. Since this is my first build I know there will be additional unanticipated expenses (there are with any project). That is also why I kinda caved in and I am looking at the Chinese stuff too.

Very cool! One question: 1 watt resistors or bigger?

Hi y'all, Apologies in advance for the novella...thanks in advance for those who can endure to the end. I'm new to the forum, and LED tech, but I build things other than this like vacuum tube amplifiers. Since my budget is so tight it squeeeeeks I have been lurking this and other cool forums...
