Yeah, I noticed no dimmer. The dimensions on this light look interesting. It's 200w spread out like the SUNRAISE, but a different footprint 23.6" x 31.4".

I watched the video on the main page since that comment and it says dimmable. My bad.

It would be nice to know what diodes they use in that light. In the specs for LED type it just says "Taiwan".

@Marq1340 if you have any codes for dehumidifiers, I could use one. The ones you posted a couple months ago are no longer valid. TIA.

In the video posted it says samsung.... That could be one diode for all we know.


And I'll keep an eye out they come by every once in a while.

I asked for a replacement, maybe I'll get lucky with the second light. Like you said for $35 you still can't beat that deal.

I'm using mine now. The plants seem to be responding well. I have it on one side of a 2x4. On the other side is a sf1000. I don't know if that makes a difference to the plants directly under the $35 one though, but it's growing up towards that one. I only have it on the 100 watt setting also.

Hey @Marq1340, you know of any deals on 6" clip on fans? If you do i would greatly appreciate knowing too. Lol

Samsung does have a Taiwan division, but unfortunately that still doesn't tell us what diodes. A lot of these cheep units use "Samsung" as a selling point, even if they aren't the standard LM301 diodes we are familiar with from Samsung. They are using diodes which are around 25% less efficient.

As of yesterday I just found these 3 but I'll check again around midnight.

Check accuracy of these hygrometer by putting several in the same jar or bag.

That seems to be the trend, at least when they don't specify

Thanks bro but not exactly what I'm looking for. I'm just gonna have to bite the bullet. Lol.


Whatever happened to the wall plug version of these? They worked great and I could get them to wrap around tent poles.

Let me know how it works. I'm trying to figure how to mount a 12" in my 4x4.

Good luck. Maybe run a board across two poles and mount it to that?

I seen something like this on youtube. May just go that route.

Yeah, a lot of them are using Samsung 2835 diodes, which aren't in the same ballpark as Samsung LM301 diodes.

Spectrum wise or just efficiency ?

Efficiency. Spectrum is ok, but LM281B+ diodes only put out 165 lumen/watt vs 220 lumen/watt for LM301B diodes. That's a 25% difference in light output for the same power consumption.

Ok cool man. That is a considerable difference.

Yep, especially if you consider the cost over a year. Let's say that you were trying to light a 4x4 space. With LM301B diodes you could get away with 450watts of lighting, but with LM281B+ diodes you'd need 600watts for the same photons (plus you get more heat along with that extra wattage). If you are paying 20 cents per KwH, that difference adds up to $120 over the year, just for a 12/12 lighting cycle. For 18/6 in veg, it's close to $200 more you would pay in power over the year. Everyone's power costs are different tho.

Right they vary, but I see what you're saying. That extra money could go towards another light! lol
