Sourcing LED drivers continues to be a pain point in the industry, as we often see that be the first failure point in Gen1/Gen2 LED fixtures. A mad chase then begins for a replacement LED driver option! Good luck finding that same specific driver from 4-5 years (or longer) ago. Which is why too often these fixtures are tossed away.
Well Keystone Technologies has been a leader in ballast technology for decades and the modern ballast is the LED driver. So it is no surprise that they have mastered the LED driver as well! You will often see Keystone LED drivers used in various other non-Keystone fixtures for this reason. This includes their Class P LED Drivers that are UL friendly. Chances are, if you can get a driver part #, Keystone can cross it.
Of course, with a myriad of driver choices it can get complicated. Keystone thus created the SmartCurrent Programmable LED driver line to be able to replace thousands of drivers with only a few SKU’s. The key is figuring out the milliamp (mA) level of the driver you are replacing, and then Keystone can either pre-program their replacement LED driver to that level or you can utilize the USB technology on the driver and tune it yourself. Be mindful of whether your driver is constant voltage vs. constant current as well as dimming (0-10V dimmable or 120V phase dimming) to ensure this functionality matches up as well.
LED Driver case size is another tricky part, because there is a lack of standardization on sizing with these. Generally the size of the case will be dependent on the wattage range, as the bigger cases can handle 100-200W max while the smaller drivers will be in the 10W-20W max range. But the driver sizes run the gamut. See the driver to get some ideas of case sizes including AF4, AQ7, W1, U7 and U4 case sizes.
As always you can check out our LED driver catalog online and please reach out with any questions if you need a different match. You can also fill out our LED replacement driver questionnaire with all the pertinent info so that a replacement can be sourced.
