How does it look? (The light quality I mean) it's really good. nice neutral CCT when both rows are used. actually i will be using the Vestas for photography/video/general lights as well as for starting plants indoor. i also have 2 F-series 4000K but they are CRI80 and therefore not as versatile. wh...

Interesting, pos to pin 2, negative 1 and 3?

i was not sure what u meant, but i changed polarity of the dimming wire on the potentiometer and now it works.

the simplest way to accomplish this is with two drivers and a linear 100k 3 contact potentiometer theoretically it should have worked because when the pot is turned all the way "up" it has max resistance (ohm) over contact 1 and 2 but minimal resistance over 2 and 3. and when it's all the way turne...

i guess the only easy way is to add a 4-position-switch. however this would only allow for toggling between cold, warm, both or OFF. not gradually adjust CCT.

do you see a way to get gradual CCT-transitioning using only 1 potentiometer or similar?

guys. as you might know there are these (cheaper lm/$ than most COBs) Bridgelux Vesta LED-modules that have 2 different color temperature LED rows. i have a few of these i want to run in parallel off my dimmable CC driver. now here's the thing: i want to be able to control the color temperature with...

LedGardener got you covered
although i sometimes still don't get all the different ways of combinations of serial and parallel

I figured I would maybe add a 700ma fuse to each strip so if one strip goes out or something happens it won't damage other strips, or cause a fire. Does anyone know what type of fuse I could use. I was thinking on getting some with leads and soldering it inline and heat shrinking it. until now i di...

update: there are a few other very cheap drivers on digikey by Thomas research products: TRP drivers.PNG for example 3.15A constant current, 10-30V, 96W for as low as $11.4 ($0.12 per Watt) ~ 5x cheaper than meanwell HLG of similar wattage, altough with 2-4% lower efficiency. UPDATE: not sure if thi...

I just noticed that the driver says max 1A as an input. Does that mean something significant?

that it will consume a max of 1A at 230V i suppose.
