  • Hello, very nice work, do you got a action spectrum chart for Indica strains?
    I am not into LED Lighting but work on a different lighting technology that is able to create all kind of spectra.
    Greetings from Germany
    Hello, i have found nice topic with your very well explained MeanWell LED drivers dimming circuits. I am trying to create alternative circuit diagram with PNP transistor using negative 12VDC PWM output as a signal. The system i have is called Fibaro. Is it possible to use your created circuit diagram with voltage regulator 7810 and PNP transistor 2N3906?
    hey can you msg me i'm trying to build an led grow light to get max effieciency and i wanna know the difference between cree3070cxa and cxb
    Hey there I was interesting in seeing cob led lights yours and if you have anything that can take the place of a 1000 hps
    Hello. I need some help measuring Tc. I currently use IR thermometer and turn off my COB after 10 mins and quickly read the temp. I do not like this method so much as temp drop 5 degrees every second or even more once i turn COB off. It is not so accurate and i do not know what i am measuring. Could you suggest a thermocouple that i can solder/attach to Tc point on COB or refer to me any thread with thermocuple info.
    Hey i wonder if you could give me a tip on which cree white chip to mix with the new cree red 660nm...i was thinkiing of using the cree cree-xte-5w in a 50 50 combination.....but i am not sure what would be the ideal kelvin temp etc...any advice you could give would be greatly appreciated.
    Hello man I'm a noob in Uv-b I'm using a 600w HPS on a 4'x4' box I'm start week 6 of bloom and plan to add a 39watt arcadia Uv-b on my box to up THC production by 6h/day trough week 6 to 8. Can you please tell me if 39watt is ok for the box and how high should I hang it? I was thinking 12" up the canopy.. I tried to answer by myself but with my low english it's not easy

    TY A LOT
    ΝΑΥΤΗ ΘΕΛΩ ΤΗΝ ΒΟΗΘΕΙΑ ΣΟΥ ΟΤΑΝ ΒΡΕΙΣ ΧΡΟΝΟ!!!

    ΘΕΛΩ ΝΑ ΜΟΥ ΠΕΙΣ ΑΝ ΓΙΝΕΤΑΙ ΑΥΤΟ ΤΟ Τ5 LED TUBE ΝΑ ΤΟ ΜΕΤΑΤΡΕΨΟΥΜΕ ΜΕ WHITE LED CHIPS.

    EΥΧΑΡΙΣΤΩ ΚΑΙ ΕΛΠΙΖΩ ΟΛΑ ΝΑ ΠΑΝΕ ΚΑΛΑ ΜΕ ΤΟ ΣΧΕΔΙΟ ΠΟΥ ΕΙΧΕΣ ΞΕΚΙΝΗΣΕΙ!!!!!!

    good day stardustsailor, positivity informed me of this site and a few members that maybe able to help me. I am a first time LED user, built my own unique system, trying to use pot's for dimming control.
    Hi man, I don't suppose you would care to visit my thread and clear up what I should try and do with regards to LED's? Your input has proven invaluable in my trawling through posts :). Take care!
    Hello my friend, I've seen your messages about leds. You have great knowledge and always give good interesting advice. Im going to build my own led lamp. I was going to use Oslon, XPE, LUxeon ES and maybe some XTE for whites. I'm still thinking about the spectrum. Many people had good results with that but some people claim about how useful hyper red 720 and purple (instead of white) or even green could be. Could you give me your advice to choose the leds for my lamp? thanks.
    Γεια σου stardustsailor θα με διαφωτισεις πολυ με την γνωμη σου. Έτυχε και έπεσαν στα χεριά μου αρκετά leds warm white .. έχω ξεκινήσει από τον Δεκέμβριο εσωτερικά με μια 400αρα λάμπα φθορίου για veg, σύνολο είναι 4 φυτά. Πρώτη φορά είναι και με τα leds και θέλω να μου πείς καμία γνώμη, αν κάνουν κλπ. Θα ήταν καλύτερο τώρα που έρχεται η άνοιξη να τα βγάλω έξω η να μοντάρω χώρο με τα παρακάτω leds εσωτερικά? Ευχαριστώ εκ των πρότερων..
