## Description

Constant Current LED Drivers are known for their easy installation and are preferable because they supply the same amount of current regardless of how many or few lights are connected to it. LEDs work safest and most efficiently with a Constant Current LED Driver.For many LED applications, it is desirable to utilize constant current drivers. Constant current LED drivers are ideal in that they offer designers more control for applications, providing them with the ability to design displays with almost no variation in brightness across the display.Chanzon constant current LED driver series is a product line with high quality.All of our power supply are CE certified in order to provide best support to your business!CE :Complies with all the Essential Health and safety requirements from all the directives that applies to our products.With certain product quality control &; verification process.Features:Product name: Constant Current LED Driver (AC-DC)Brand: ChanzonHigh Quality: Isolation Protection with CE Certificate, No Noise, Long Life SpanInput: AC 100-240V 50/60HzOutput Current: 450mA (Constant)Output Voltage: 12-20VEfficiency:more than 85%Size: 72.3*29.1*22 (mm) / 2.85*1.15*0.87 (inch)Net Weight: 30g / 1.07ozHigh Power Factor(PFC):more than 95%Kindly Reminder:Please be aware of the positive (anode +) and negative (cathode -) of led products, install accordingly to avoid damage.Do not exceed the maximum voltage or current,otherwise the led Diode may burn out.

Review: Learn from my mistake - I used this to repair an older led pole light. I think they are still being sold here under the name Torchstar. It has a good cast aluminum case that kept water out fine, so I'd like to keep it around. The original driver stopped working, and there were a few individual chips burnt out. Took me a lot of probing and checking to determine the way the leds were in the circuit. No information on the original driver. For this light, it was 75 leds, three parallel branches of 25 leds each. So around 75v drop and 450ma driving the three branches seemed about right. After replacing about four chips last night I hooked it up to the driver and it came on fine and all chips were on. Today I wired everything back into the lamp, cleaned off the old heat transfer paste, put new paste on, and put the repaired panel back into the lamp. I put power back on it, and it came on great again. Then it shut off after a few seconds. Then it came back on for a couple seconds. Then back off. Strobing. Great. I didn't have it on much last night and kicked myself for not just plugging it in for 10 min today to check it before I put it together with the heat transfer paste that is incredibly messy. I thought the new driver was not handling all the leds; and cutting out and back on. Miffed, and wondering about a return or if it was worth checking the voltage on it, I was about ready to chuck the whole thing into scrap metal. I then had another thought. Couldn't be that simple. I held my hand over the light sensor and plugged it back in. The board came on. And stayed on for 5 min. I took my hand off the sensor, a couple seconds later the light shut off. Then a couple seconds after that it came back on again. So DIY'ers, remember that dusk to dawn sensor that you cleaned up and checked weeks ago and made sure it worked? Well as luck would have it, it still works when you wire it back into the circuit. The light was coming on, bouncing around the white walls of my office, and then tripping the light sensor. Then the room, still lit but not bright enough apparently, would be dark enough to turn it back on and start the cycle all over. The driver works fine; fits good in that lamp I mentioned. No idea what kind of longevity it will have. I will probably keep this as a spare. Happy now.
Review: Great Driver - These work as advertised. While they do work great with other COB lights I recommend that you use the Chanzon lights as they are more reliable and longer lasting.

### ⭐⭐⭐⭐⭐ Great Driver
*by J***N on December 18, 2025*

These work as advertised. While they do work great with other COB lights I recommend that you use the Chanzon lights as they are more reliable and longer lasting.

### ⭐ VERY Disappointing!!
*by S***M on August 10, 2017*

Very Disappointing! Advertised as "Constant Current" driving 1 to 6 1w COB LED's. So I purchased this for a project with 6 X 1w COB LED's (from the same manufacturer) requiring 300mA each. This driver does a great job driving ONE bulb but as each subsequent bulb is turned on it goes downhill. Just a quick test- 1 Bulb 3.26v 2 Bulbs 3.05v 3 Bulbs 2.92v 4 Bulbs 2.83v 5 Bulbs 2.79v Did not test with 6 as the 6th port was occupied by my Fluke meter. So certainly not providing constant anything from 1 to 6 bulbs and with 6 bulbs all turned on the light output is very minimal and undetectable at 24".
