I knew that was cookies or a cross as soon as it popped up. Super cookie dom looking. Hate to say it, probably won't get much bigger. But the rest of the garden is large and in charge. The mid to late 40days are the best, still so healthy, but have the size and girth.
Thanks GG, that means a lot coming from you! Ill save the cookies for the private reserve, scrap the clones, and make way for the new gear. Bitches be addicted to buying shoes, growers be addicted to collecting seeds, lol I just popped some Exotic Genetix:: Cherry Cream Pie then I saw seedsherenow has a pre-order on their next drop. So I got Grease Monkey and Pink v2. I have been wanting something with Starfighter genetics in it for a while now.

yup. thats the price I had to pay. sorry germany.you are using unlicensed music in your vid, gets blocked in germany
It's using the pwm to switch the firing of scrs to decrease output current. It isn't flashing on and off
In a PWM driver the current is is switched at a high frequency between 0 (off) and rated output current. This means the LED load is either off or or running at its rated current. Example 1000ma driver using PWM to run at 25% (250ma approximate equivalent) the signal would be @ rated current 25% of the time and off the other 75%. The ration of on time vs off time is what determines the LED brightness. That's always been my take on PWM as far as the electronic theory behind it. If Meanwell is using some other proprietary method or something please point me to the link or documents to support this so I can learn something new
You are correct. I was thinking of CCR. Constant current reduction. Here is a little write up I found to explain what I was thinking. But meanwwell does use pwm to dim so it's not really applicable but some info none the less lol. >In a PWM driver the current is is switched at a high frequency between 0 (off) and rated output current.

thank you here's a pic to show ![IMG_20151003_183941291[1].jpg](/data/attachments/2612/2612563-ae2204d9a2d468b022b0ab4c328a34e9.jpg)
fired up the HLN-40H-54B to 20 xlm 10w with no pot..i think im gonna need a more powerful one, it's pulling 60w @kilawatt meter and looks weak,

since im such a newb and old and lazy LOL
what is the next powerhouse option that i can dim down..if there's any
WwW SINCERELY
mucho graisa's amigo i couldnt find the first one on mouser, headroom for later would be the bomb..make into a full blown on vegging light, like u once said before, i hope im not clogging up your thread with this stuff thank you again GrowMau5

i have 20 in series. going to add 10 more .i was thinking 3w a piece..you guys know all about this stuff
thanks for making me retest, i disconnected 1 lamp and it's twice
keep in mind, as you run your xmls at a higher current, their forward voltage will increase from 3.0v to around 3.7vi have 20 in series. going to add 10 more .i was thinking 3w a piece..you guys know all about this stuff
well i just tested it again, never your right, it's only pulling 9.3 watts and running at 60 hz
120 v i told ya i was blind ..
as bright now pulling 38 watts..
i'll keep one as a spare thank you GM
must be sumthin about the xml specs, cause I built a light with xml 2s and even after using the data sheet for a normal max Vf to spec out the driver, I ended up having to disable a couple of the chips or the driver would go into limp mode.
MW drivers use PWM only as a mean of transportation of the signal. Actual dimming is done by reducing the current. It means that the efficiency is the same no matter whether done via resistance, PWM or 1-10VDC.
That's what I suspected but I'm glad to hear someone else say it
