Led lighting confusion

[oreo54]

It does not matter if the data sheet is absolutely correct to the decimal point. Generally 3W LEd that are not Red operate around 3.5V with 750mA current range. You can not check the current at the moment as it does not have a sufficent voltage across the LED, from what I can understand.
Anwyay, you are not trying to tackle the problem properly. Get a way to produce 56V (50-60) DC independedntly and if you want check the amper range to make sure.
IF NOT get a LED Driver, with the spec I have already mentioned. I seriously don't undestand why you would not get a LED driver that should be quite cheap and easy way to solve this problem....

Hmmm never read anything about problems w/ "under-driving" led's except for light loss of course.
Less current, less heat..

Tecnically a good tradeoff is they run more efficiently..

Because my issue isn't for the single channel. I had a 5 up board from an old light that got fried and just ordered a 5 up 500 ldd board 3 days ago. Now I will have the number of individual drivers I need but at 500 mA, not 700.

I set this project up to switch my lighting from t5 to all led. The PSU is 48 v which I can adjust up a few volts to compensate but the max for these drivers is 56 and the next step up in available psu that I saw was 60 volt, plus I'd rather not push the upper limits of an electrical circuit. So, here I am with under powered drivers, spending way more than I had wanted because of the first 5 up board that was shot and now needing to push higher amps and upgrading my psu.

So I can't afford the extra 45 buck or whatever it will cost for another driver board with the drivers.

Well the LED drivers I'm talking aboput cost around $2-3 here not $45. But maybe you guys dont have access to chineese stuff over there.
Here is a link for example where you can choose and buy 500,600,700 or 750 mA driver for $3.
Here is link for online buy
If you in that much of a pickle go for 500mA with around 50V. But that will produce a lot lower illumination level than what you desire.

Well it will not be a problem untill a certain point. But afterwards due to the fact that Diode junction not receiving enough current to operate properly diode will operate flickering and under sub optimal conditions. This could leave to again a burned LED before its optimal usage periode

Each driver isn't, but we need to pay for a driver board, plus the meanwell ldd, and the shipping charge. The meanwell ldds cost about 7 dollars each. And the boards are between 10-15. And shipping is at least 10, then take bring its up.

So all in all, it's probably better to use the types of driver boards you posted, but the meanwell ldd allows dimming, which is a nice option that I have included in all my other channels
