    Ok I'll keep it under 48V max. One last thing a few drivers have input V of 180 VAC to 480 VAC. If i'm in america i want the 90 VAC and above?

    I just borrowed a multimeter, can anyone quickly teach me how to test what the actual voltage and amp draw is for these circuits?

    I'm just not certain whether these drivers are providing 12v or 24v, and if I would get more intense light if I replaced them with proper 24v drivers...

    I have the strips wired in series, but I'm not exactly sure what these drivers are outputting, and so far I've only been able to test them using a Kill-a-watt meter, which just shows the use as 120v / ~50w / ~0.43 amps for the 2x2' strips.

    EDIT: The drivers actually have 2 outputs, 1 for a 12V case fan, and the other lead was meant for a section of LED diodes in the fixture. I measured the output leads meant for the fan, and it read NEGATIVE 12V. When I did the same test on the leads that were connected to the LEDs, I get around 85V and it doesn't show the negative symbol... There were actually 3 of these drivers in the old light, and it was one of those mars II style chinese lights rated at 1000w, but I don't think the actual draw was anywhere near that :)

    So how about a pic of that driver? YouTube is your friend on your multimeter.

    And whats written on yours? Or no sticker?

    Edit: 2 strips(2ft) = 50w (what you measured was AC)
    1 strip = 25w = 1050/1100ma = 22.8/22.9v

    And actually I wouln‘t have words to provide you a proper lesson on how you use a multimeter. But for me, youtube video worked wonders... 15min and I was already able to measure everything. But to be honest, I started with a battery, just to be sure (:

    And I got a question myself, using one HLG-60H-24A now on 14 strips in parallel. If I want to double the power, can I take another HLG-60H-24A and put it in parallel on the other end? I read about it, but I am not sure, if I got it correctly (was it parallel, or series?). They used two driver from both ends, to power a very long strip, so they didn‘t had a power drop at one end. If that is workng, it is also working with a diffrent driver, e.g. HLG-120H-24A?

    The 50W / 0.43 amp reading was with a Kill a Watt meter, so I'm not sure what info that gives me? Guess it means 50w is the draw from the wall, but that doesn't mean that the strips are running at 25w each? And if 2 strips are running at 0.43 amps and they're in series, would that mean that the amps are the same for both strips? "

    In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component."

    I hate circuits....

    Crap, looks like the photos in that link don't match the model number...

    My label has Morsen in place of the NL logo, and says Model: NLGI-100XC-063A





    Input: 100-240VAC

    50/60hz <0.9A PF>0.9

    Max. Output 150W




    The driver has a black/red wire on the left for connecting to a power source, and 2 pairs of leads on the right side, 1 of which was running a 12V case fan, and the other lead was running a section of the LED light board.

    OK, I'm running 22 1ft strips in a 3x2 (39.5"x 22"). Which configuration would be better for optimum coverage ? Running 3 strips on 36" heatsinks the width of the cab or just (22) strips on (22) 15in [​IMG][​IMG]heatsinks across the depth leaving a few inches on each side? I ask because the 1 ft strips configured won't cover the 2 ft depth of the cab and would have to be centered. First pic is strips configured length wise second width wise, Thanks just looking for the most complete coverage

    Spread em out! Instead of mounting them like in the bottom picture, you could mount one strip left side, one strip right side, and so one. But I also like the top config, but if you miss strips, take them out of the middle, to achieve a more even illumination.

    StreetPreacher Member

    I'd also say spread them out. I mounted 2 strips to the underside of my metal shelving, and just 2x2' strips seem nearly bright enough to keep a 3x3 space of clones on life support.

    And the driver label is in my avatar, it has 1 pair of leads for power input, and 2 pairs of leads for output, with 1 pair intended for powering a 12V 0.28A DC case fan, and the other leads were powering 1 section of a 1000w rated "Morsen" chinese LED fixture with the red/blue/etc individual diodes... The fixture had 3 drivers, each powering a separate section of the LED light board.

    You must make sure that you are using a suitable driver. Meanwells are usually suited to work in all countries.

    Kaneh_bosm Member

    Sounds good alternating pattern. Thanks guys I'll keep you posted o the progress

    To double the power using a second supply, just put 7 in parallel on each one, and adjust them until the current is maxed out (assuming the single driver is running at max current now)

    Have you ever mixed strips of different color temps. 5000-4000-3000k in same light or variation ?

    I have "lamps" with multiple K temp mixtures, 560mm EBs. My first batches we're all 3500k, then I added some 3000ks later.

    Serva Well-Known Member

    I have 8x 5700K + 4x 3000K (4800K) and flowering with it, pure 3000K as supplement for my panel for flowering (~3200K), and different combination of 4000K + 5700K as veg and clone light. The gen2 strips I have ordered are 50:50 3500K + 5000K (would have prefered 5700K, but these won‘t be avaible soon) (4300K), and it will be veg and flower light, adjustable in spectrum via 2 drivers. And here is what I am doing right now:
    I was looking for an app to draw a sketch for my wife, and found a pretty good one actually, it makes fun, and isn‘t frustrating! Yello strips are 3000K, blue ones 5000K (3700K). But it will be used to farm spirulina algae.

    But yeah, I love mixing strips, instead of taking the average as spectrum.

    , I'm a fellow Canadian and I seenyour post

    I'd like to go twelve strips but only two feet wide as I only grow with 2x4 tables to ease of access I have a terrible back.

    Here's my current journal, scroll to the bottom up the latest pics

    But basically it seems youve done the legwork on this led strip diy in canada. Sourcing in canada isn't easy.

    So I'd love a little input on my build if you don't mind.
    So 12 of the 2 foot strips.
    6 3500k
    6 3000k

    2 drivers
    I'm just confused on how big of a driver IL need for 6 two ft strips of each color.

    Also do you think this will be enough for flower

    Roughly 2x4 = 8 sqft, 30-35w/sqft = 240-280w. So I would look for 2x HLG-150H-24 (so I can adjust the spectrum better, and don‘t need to run both driver full power). With the A version it‘s dimmable between 50-100%. 6 strips at full power (150W), 1100ma, 23v, 25w for each strip. If you had the money for these expensive big driver, better double your strips, and take these small driver ;)

    So 12 two ft lights would be enough for flower? Or are you saying use 24
