A driver for SunLikeMASS15D

I bought two Sunlike MASS15D bulbs from Lampman before he was jailed. The other of them arrived broken. It seems that one can not get new ones, so I’d love to repair it. After I disassembled the bulb, it seems that the problem is with the driver, but I could not find anything physically wrong with it.

The driver is Triac Dimmable LED Driver, Model: QH-LK7-20×1. I could not find information on the specific driver or a way to purchase one, and wonder if some other driver would fit. I’m not very knowledgeable on the drivers so any input would be appreciated.

I have a small bulb from him that died after turning it off/screwing bulb, then turning it back on couple days later. I think the driver wire may have disconnected though, as the driver shakes around. haven’t had time to try to dismantle, but the e26 screw will be ruined in the process for sure

I only like high CRI. Collection:

Fireflies NOV-MU 21 4500k E21A

Fireflies ROT66 219B SW45 D220

Fireflies E07 Copper 219B SW45k? (odd/higher lumen bin with lower r9 and higher cct?)

Fireflies E07 219B SW45k

Fireflies E07x Pro sst20 FA4 4000k 

 

Varmint removal:

Convoy M21A C8 ver SST20 4000k (5a)

Convoy S2+ SST20 4000k  FB4 (3200ma)

It had something to do with the Lukashenka regime. He was apparently jailed for for speaking on the Internet about an employee of the Ministry of Internal Affairs. He posts updates on the SunLikeLamp.com Telegram channel, but I don't speak Russian. https://t.me/sunlikenews

 

And thank you! How should I go in buying the driver?

The driver says it is a Triac Dimmable LED Driver, Model: QH-LK7-20X1 and the PCB says QH-LK18W.PCB.

It is possible to carefully remove the E26, or E27 in my case. One can also buy them for almost no money from China or find similar ones from some other LED bulbs.

I know he was getting his hosts and drivers from taobao, he posted a few links somewhere, maybe his other blog, but I’m guessing only vk one is alive now

This seems to be the correct one. The driver I have seems to have a an added thermistor and two film capacitors that I can solder to the new one. Thank you so much!

Is that capacitor dead? You sure it’s the driver at fault?

Sadly I don’t have the means to test it properly, but with a cheap multimeter it seems to not be completely dead at least.
