Lighting Chinese 50 Watt Full Spectrum COB Chip - No Driver Needed

Just buy a migro led light, it'll save the hassle. Has all of that dimmer switch stuff plus u can adjust the angle of it, its not fixed down. Brilliant piece of kit
 
If ya wanna dim KAHBS just use the 0-10v dimming circuit with a 100k ohm potentiometer with the 'B' series drivers. BOURNS brand works great....available from Arrow and CobKits.com or go with the 'A' series for a built in mini pot. Much of the Mean Well product family including the HLG series are factory dimmable as well as my LG Innotek 4 channel driver from a dumpster with a Cree quantum board!!! That's a good find....lol

There called KAAHBS Joe
 
Meanwell makes dimmable drivers and with more than one type of dimming, internal, external and PWM that works with Ardiuno. Autocobs were built without for simplicity. Dimming on a large fixture is a good idea, on these single cob lights, its a waste of time, you want to have to mess with 4-8-16 lights to dim each? There is an easier way............ raise it or lower it to adjust the light! Sometimes, simplicity is the best answer!

And migro is overstating its specs, I call bullshit! "PPF/Watt: 2.2 µmols/watt" ohh sure, but NOT at 100 watts, no cob made is that efficient at that power level, more like 1.7 to 1.78 at best. They are stating the ppfd @ 25-35 watts, NOT at rated power. Its easy to lie with statistics to those who don't have a working knowledge of how the specifications work.

Re: Bold.

And here endeth today's "Stating the bloody obvious" lesson, why make things more complicated than necessary provided you have the space to raise or lower the fitting?
 
Physics is as powerful as a potentiometer. Par meters really prove this and just so happens I supply adjustable ratchet hangers too. :thumbsup: Electricity savings sure but when dimming a cob to save energy it’s almost like not using ur headlights on a Prius to save battery life. Ya feel me?lol. Simplicity is key and it’s beautiful too.

I am the number one fan when it comes to efficiency but I have learned the hard way over the years it’s not really as important as the years it may take to recoup. “Dalcnet” wow!! I don’t understand how two leads that carry amperage and voltage can be dimmed separately. Not doubting you one bit but I’m surely not smart enough to figure it out. The price! 106 on flea-bay. Kinda my point. Dimming a cob to save a small percentage of energy but spending 100+$ to do so is something I wouldn’t expect to often. Nevernind the work and where the heck do you put it problem. @pop22 2.2umoles/what* lol.

Well, as I say, the + and - from the driver go into the "DC In" and then your LED gets connected to the "Out L+ L-". The Normally Open Push to Make switch or remote module or whatever, goes onto the "0v" and "In" connections, then you power everything up, push and release the switch to turn on, push and hold and you'll see the light go through the full range of dimming from "off" to "full" and back again. You let go of the switch and the module will stay at whatever brightness you have decided is "good", then tap the switch and it will go off. Tap again and it will go back on at whatever level you set it at, same applies to cutting power via a timer or whatever.

I think the most we managed to squeeze through one was 90W at 24vdc, above that and it can start flickering just like if you were over the upper limit for a driver, but 5m of 14.4W/m LED strip, as in 72 actual watts, was not an issue to this wee beastie..

What the electronic gubbins inside them does is beyond me, but I do know they work VERY smoothly with a very soft dim curve to "off" and not a sudden "cut" to darkness.

As I say, I know they are expensive but they are modules I have used hundreds of times. Obviously they're not the only ones out there but they are the only ones I have worked with and the only ones I can honestly say work without issues.

PS. At the price you're seeing I think you may be looking at the "Bluetooth enabled" version, as I can see the basic module mentioned above on Ebay at around €34 plus delivery, or roughly $41

I have used the 110v cobs. They worked but not very good. Took 9 50w chips too grow one plant that was 4.5 ft wide and 2.5 ft tall. In other words.... They suck!

I still run 6 to heat my room. Each chip will run at 140f. But a total waste of money and time if you want to grow with them.
