Hi
@Berulakide , the light of yours is the old version which is the 5w chips, the newer version is with new SMD chips, we upgraded from last year. So if you order before the middle of last year, you might still get the old version light.
Chips are all 5w ones, please don't worry, just the soldering type is different. (older one with lens, the newer one without). And 3w or 5w actually is for led size, not mean the led is really 3w or 5w. Some of the seller take this name and misleading customers mentioned 10w chips, they are actually not real 10w as well, might be as the same as our 3w or 5w version. Look at the real wattage on the specification, and you won't be misleaded.
As to the lgihts, we cannot trade in since the light seems used for a long time, and we also don't have trade in programme. Please don't worry, no matter the older version or the newer version, our lights are ETL certificated, and all the materieal are anti-fire, safe to use, they are not dangerous, we have many grower uses our reflector lights without any problem, just getting good results.
If you don't know how to replace the replacement parts, you can also send the light to our repair center, and we will help you fix accordingly
And a kind remind: as the light is not waterproof, also growing environment is special, it will be better you can clear the light now and then, it will help lengthen the lifespan of the light.
