I measured those types of LEDs a couple of years ago with a quantum sensor. Watt per watt they deliver about a third of the light delivered by a panel with Citizen 1212s. With regard to the light mover i don't know how it will work. Physics laws of conservation of energy and mass says that you...

They are not worth the time or money.

Looking the input power an HLG-480H-54 is your best match but you need to know the output current to be sure. It would help if you can give us the driver model they have installed to be sure.

All 100H-30 will work. I would keep the Thomas, the difference between both driver in terms of energy savings is around 4.7W; where I live, 1kWh cost around 15 cents so with $50usd(50/.15) I can pay 333kWh. If I use these light with a schedule of 18hrs per day, will take me 11 years to use...

Both drivers are constant Current and deliver 3.15A so you will get the same power output(around 95w) and looking to the specs, the Thomas have a better efficiency. The 114W input power is how much energy is consuming (the AC side) 95W/114W=83.3% efficiency vs 89% from Thomas. If you want to...

You are right, to dim your lights you can use the built in potentiometer instead the 3 in 1 dimming function.

The question is if they worth the price. I couldn't find the price for gen 2 3000K(in stock was 7.5USD)so I will use the 5000K price in Digikey, 8.40USD each. For gen 3 the price is 14.175USD. 20 Eb gen 2 will cost you $168USD, @700mA 27.3W(546W), 4780lm(95600lm) 20 Eb gen 3 will cost you...

@35w sq ft and if you want to drive them @1000mA you will need 14 strips, you can power them in parallel with one HLG-600H-42 A or B type. @700mA you will need 20 strips, same driver

Much better the first one, Wich one you need depends on ambient temperature and the temperature on COB's junction.

May I know your proyect with these LEDs? 2.8V@75mA=0.21W x 40=8.4W Basically you can drive them with a 12V 1A power supply and a resistor to limit the current.

You are wrong, LDDs are constant current so each string in parallel will get 750mA. You can wire them in series direct to the LRS but you need at least 16LEDs in series and a multimeter to set the appropriate Voltage according to the selected Current.

If you want to get the max power output from those drivers your choice are the Vero 18 D, to run the CXB3590 you need to connect the outputs in parallel adding currents. CXB3590 at Tc=50°C 34.4v@1400mA=48w and you can connect up to two COBs(96w)per driver 35.7v@2100mA=75w, one COB per driver...

To run a CXB at 80w you will need new driver

Two Vero 18 D in series fit perfect, around 28v each COB.

Am talking about Vero18s. In series voltages are added, so if he said "splitting the 64v through two chips" am thinking in series(32v per chip). Not enough for that driver.

Vero18s(B and C)have a forward voltage around 34v-34.5v at 700mA. If you put 2 in series(68-69v) you are exceeding the driver output voltage. The new Cree CMTs have 54v and CMAs 48v
