How many Cobs can be driven at low current?
Please note that even though big drivers may be capable of driving tons of COBs in series at low current, the high voltage generated by wiring the COBs in series may exceed the rating of your COB holders or connectors (a number of common holders are rated for a maximum of 250V – this would equate to a max of about 7x 36V COBs in series per driver).
What kind of current does a led need?
LED Drivers LED drivers are the handy little boxes that take the power from your electrical outlet and convert it to a form that the COBs can use. The electricity coming from your outlet is alternating current (AC), and this does not work for COB LEDs – they require direct current (DC) instead.
What’s the maximum current you can put on a cxb3590?
The maximum forward current rating lets you know the largest amount of current you can apply to the COB. Referencing the chart above again, the maximum forward current for the 36V version of the CXB3590 is 3,600 milliamps. Common drive currents used for COBs like this are 700mA, 1,050mA, 1,400mA, 2,100mA, and 2,800mA.
How to calculate the LED power supply needed for your led?
The LED strip has a power consumption of 14W / m. 14 x 8.5 = 119 Watts in total. So you need a LED power supply (sometimes referred to as a LED driver) that can deliver at least 119 Watts. However, it is recommended that you make allowances for unintentional overloads.

What do you need to know about led current rating?
Ultraviolet. 3.5V. LED current rating (mA): The amount of current needed, in milliamps (mA), for the LED to light properly. This value is usually provided by the manufacturer. Also known as forward current. If you are not sure of your LED current rating use 20mA for common LEDs.
