Yeah sorry, was having a hard time finding the tabs after my kid messed with my computer. The one with built-in shunt and which is possibly in series is this one...

Thanks, I am still trying to learn the weird relationship between diodes and their power supply; they're not quite resistors, not capacitors, not transformers, and really not even completely like other semiconductor products. For such a simple device, the nuance of it can be surprisingly...

Sorry, I know this is an old thread, but how has the laptop power supply worked out for you on the EB strips? I am considering running 8-10 of the L0280Z size strips as side-lights and running them off a 7.7A 19.5V Asus laptop supply. They seem to be constant voltage supplies, but I don't know...

Sorry for any confusion, but what if you don't have an A-dimming MeanWell driver? I do own one, so this is somewhat hypothetical, but there's so many thousands of different drivers to pick from.

Here is the EB Gen 2 data sheet for reference: https://www.bridgelux.com/sites/default/files/resource_media/DS131%20Bridgelux%20EB%20Series%20Gen2%20Data%20Sheet%2020171020%20Rev%20A.pdf

I just realized something... the BXEB 280mm modules are rated at 19.5V, which appears to be right in the middle of their allowable voltage window. I just so happen to have a significant supply of laptop power supplies including one that is 19.5V and 8amps(I also have a 10A unit but that's in...

If each one is on overcurrent protection, wouldn't the current limiters stop the others from suffering overcurrent if one of them fails? Sure, it means they all shut off, but they don't fry right? I can get current inrush limiters that are 700ma or less so if one was on each strip wouldn't it...

I am trying to better understand protecting LEDs from overcurrent. I have considered the idea of using low-current breakers(but the lowest I can find is 2.0A, so not low enough for individual strips for example). Then there's also inrush current limiters(but they have a resistance, so they're...

Can't upset Mrs Beer :D I have to say that these ladybugs really impress me sometimes. If you give them conditions to keep hydrated and fed; they will clean your plants incredibly fast. I had one plant yesterday that was covered in some sort of scales/barnacles and the ladybugs have demolished...

I have decided to go with the BXEB-L0280Z-35E1000-C-B3, but I am still figuring out what driver to run it with. I am probably doing 8 of these, but I might do 10 if I can find a driver that is reasonably priced and can run all of them. Each says it can handle 700mA max, so I was thinking of...

I was thinking more of a household variety.... lol

LOL yeah I don't mean tropical megapedes LOL

I use those fake lady bugs and they do the job really well, but they're really dumb and wander away from the botanical paradise to die in a crack in the wall somewhere. They're incredibly dumb. By far the biggest pest killer you can unleash on a garden is centipedes. Centipedes kill hundreds of...

I found them with a microscope. Sometimes a single plant may be more vulnerable or a vector only made it on to that plant. I had just one plant out of all of them that just got barnacles all over it recently for example; I only spotted the first few because I was doing a routine check with a...

The damage and the recovery all make me think of root damage as a culprit. Have you checked for root aphids? They can be really insidious and the damage they do is really inconsistent(some weeks its much worse than others). I spent months trying to figure out what was wrong with one of my...

Here's my journal for my latest grow project. I have built a 2x2 and put a QB96 V2 in there with plans to add some side light strips. Since I don't want a separate discussion page; please feel free to discuss here. I'm a medical user living in a regressive state, so we're working toward getting...

I have no idea what his fate in the long run was, but that guy definitely got cooked that day. Its a funny story actually..... My friend owns a business and they were hiring an electrician to modernize some of their 3-phase gear. For some reason, the electrician they hired sent a guy with no...

It definitely is hard to get conduction through the body at 54V, but if you can manage it, that current is 34 times what the generally accepted lethal threshold(0.1amps). I did see a guy almost kill himself on a 480V industrial panel. He had smoke coming out of his ears! That's quite a story...

I should also add that running things on GFCI circuits with lots of overhead and grounding on all your equipment; your risk level drops enormously. Its funny that I think some of the most daunting things with DIY is figuring out little things like what wire to use, how far back to strip it, how...

Oh no doubt there are dangerous currents involved. My Mean Well HLG-185H-54A can deliver at least 3.85A at 54VDC. No joke, that'd kill an elephant. That said..... the DIY stuff for LEDs is ultra simple as far as electronics goes; compared to an Arduino project or a battery management system its...
