i'm actually talking to a family friend that's in the led industry for 15+ years to make my own lights since so far on the market i haven't seen a light that actually satisfy what i want...there is the Chinese lights that are ok and cheap but the quality isn't there. and there are lights with nice quality but will charge you an arm n a leg for it. that's why i started this poll to see what the growers are actually looking for
). It has a very nice dimmer knob on the side and nice quality build for sure. Been impressed by the 2020 line of lights from them
i'm learning something new as well...apparently all these soo called ir diodes or uv diodes don't really work that well, and the ones that does actually work cost alot and has a short life span. another thing i learned is that everyone is all hyped up on the branding of the diodes but little do they know even though alot of them claim to be top bin diodes, are they really? as for the samsung lm301b or lm301h, they are both on contractor grade. i'm trying to do something that's designer grade, but will prob built it for myself to see how it actually works out since i'm very anal about the numbers...hahahahaIn my 4x2' use a 240w 3000k+660nm Samsung lm301b qb light from China, ordered on amazon, meanwell driver, seems to work fine, but I agree the quality isn't there, just bare utility for sure in that. I also have a 150w viparspectra p1500 in my 3x2 cabinet, if I remember right that's mixed 3500k 6500k and 660nmk together, but new versions include IR (mine however doesn't
Price was a big point but I wanted something with not terrible coverage also, and since my grow spaces aren't very big I didn't feel the need to get the expensive brands.. the ones I have were around $130-180, not sure current prices.
how much was this?
i've used a light like this before...make sure when u turn it off you don't have any pressure on the plastic infront of the LED...the heat sink is pretty bad n it actually made the plastic covering change shape.
that's good to know...but ya...the heat sinks on it is really bad.... i had my 800 hanged i think 20" to get 1000 ppfd in the mid
TBH I have no used that light. I run Gavita and Fluence. Your Nutrient demands will change at the PPFD increases. Also they will require Additional Cal Mag. In Coco I have to run about 7 ML per gallon for the first 3 weeks and drop down to 5ML until the 5 week of flower. Also the chart you posted is a PPFD chart. The light is advertised as 1842. This is suppose to be the average across the whole foot print. Meaning if it is shown to flower a 4' x 4' area the average would be 1842. The highest on the chart is 1394. I am afraid there is some false advertising in the paperwork.
