I've just built a fixture using 8 one foot Vesta strips and two of the cheap Digikey Thomas Research drivers. All mounted on 25mm x 2.0mm aluminium square sections in a frame. Works out at 375mA per channel. One driver per colour channel means I have spectrum control. The amount of wiring required g...

If you have a decent multimeter you can test the circuit and use the voltage adjustment knob to stop thermal runaway.

Then keep adding cobs and splitting current as funds allow.

Hi Eddie. You will be fine to slightly exceed the connector rating. Potentially you could solder to the strips directly if it is a concern though. The voltage rating on the connector is simply a reflection of the insulating properties of the connector material. Anything under 300v/9A is normal and c...

They are for remotely turning on/off the driver from an external input. Normally a voltage.
Seal them up with a heatshrink tail or throw a connector on them if not in use.

I like them because its easier to load the driver to 100%. I always feel a CC driver has some wasted potential as you can never match the load to the max voltage output. They're also a good option if you want to scale up your light over time. Start with three cobs. Then go to four then to five. The ...

That Vero would be more like 37.6v at 2.1A, so almost 80 watts. https://nz.mouser.com/ProductDetail/MEAN-WELL/ELG-100-36A?qs=sGAEpiMZZMt5PRBMPTWcaaMIEBR%2fZ8x2Ire1rMMCIGrLTLSO1kcbCw%3d%3d Sorry for the link to the NZ website - this A type driver has two pots so you can adjust the current and voltage...

200/9=22.2 watts per square foot - I'm thinking you're a little short on light there to get the results you're after.

Your light would look nice with a quantum board smack bang in the middle of it too.

To dim a driver normally means a slight loss in efficiency as the load decreases. Meanwell HLG's are VERY efficient but do run most efficiently at full; or close to full load. I'm not entirely sure I understand your question re: current otherwise. 2800mA is outside the efficacy range of those Cree's...

Hey maaaaaate. Great to see another Kiwi on here DIYing. Strips might be the go for the vege/clone/mother areas but I would recommend COBs for your flowering area to get those HPS like frosty nugs. Especially given your 2 metres of headroom. Digikey and Mouser both do free shipping on orders over $6...

Sounds like a good amount of light for a 3x3. I made do with less than 30w/sqft with good results for a short while. Using the light for dual purpose vege and flower, I would mix spectrums (some 3K and some 4K/5K) Straight 3500 just seems to lack the red to really drive flowering however this is com...
