Hi
@Spiderfarmerled, can you clarify some information for us regarding your G series and SE Series grow lights?
I've done a bit of research, though it appears not all of the information is being provided, and if it is, there's a lot of inconsistencies with said data. I won't go too in-depth about this, but I want to clarify a few keypoints, as I couldn't seem to find clear, reliable information online:
- What model Bridgelux diodes are you using in your G-series lights? I assume their horticulture SMD chips? (2835 0.2W (21L-3DA))?
- You mentioned, back in March 2023, that your G-series requires more diodes to meet the same wattage output as the Samsung diodes, though there seems to be a significant difference in diode count per watt between the G8600 and G1000W, as example.
- Based on the above, the G8600, while having a higher Wattage output, has less diodes per watt when compared to the SE7000. I am not certain if I am calculating or working this out right, though something doesn't seem right, to me, as those numbers don't seem to add up.
Comparing the G8600 and SE7000, you can see the SE7000 has more Samsung diodes per watt compared to the G8600 light, which ends up having less diodes per watt, however, the G1000W has significantly more diodes per watt compared to the G8600 - to me, being a complete idiot with LED lights and their specifications, the G8600 seems to be very bad value.
Based on this information, it almost seems as if the Bridgelux chips are being powered slightly more - based on your comment (linked above), it would insinuate that the Bridgelux model lights require more chips to compare with Samsung.
However, the diodes per watt indicates otherwise. It, in-fact, indicates that perhaps the diodes are being ran a bit harder than the Samsung counterparts. Again, this is simply basing my theory on your own comment surrounding the fact that Spider Farmer manufacturers the G-series lights with more diodes to compensate.
Unless there's something I'm missing, I'd appreciate if you could chime in. It's VERY DIFFICULT to compare model lights, as you don't have all of the information side-by-side. Essentially, I am trying to understand what light is going to "last longer", based on how the LED chips are driven.
I'd also recommend putting the specifications of each light's driver (make/model, etc), so buyers can make more informed purchasing decisions.
I've seen your chart showing the difference between the SE Series and G Series lights, though this still doesn't really put things into comparison, as in my eyes, I'd be best off going for the G1000W over the G8600, and the SE7000 would be a better option over the G8600, as my assumption would be that the G8600 diodes are being driven harder.
I sincerely hope you can clarify these things for me, and perhaps the community, as data is critical, and providing accurate, meaningful data is very important. Once I have this information, then I can make better purchasing decisions. I don't want to be stuck with a light that fails prematurely due to diodes being powered harder, if that makes sense.
Thanks again team, and I sincerely hope you can clarify this up.
EDIT: You also don't mention which binned LM301B diodes you use, as they have 70, 80 and 90 CRI binned chips. Can you please clarify, as this is also a very important factor.
