SKV89's LED Strips and bulbs test results

Copied. Seems to work this time. Thanks for the help!

Thanks a lot for the info. I see that you’ve got a couple of ordinary fakes and that CRI95 lights often are slightly short of their rating but most strips easily do 90+. :slight_smile:

Good job ! Thank you !

Great, thanks. You mentioned using 240v… but you’re in USA. Why not 120v?

Sorry I meant DC24V and DC12V

Many thanks for this numerous and impressive work SKV89!

Do you think you could, progressively, publish the missing R12 info? It would be perfect to help fill in our "BLF Ultra High CRI table".

Hi fneuf. Since I have all those strips stored away, it will take a lot of time to pull each one out and screw on power adapters to connect them. Therefore the chance for that is unlikely given how busy I am. But from what I remember it is always the R9 that is the lowest so R12 should always be higher.

Which Auxma 2400K 2835 where your favorite, SKV?

1) Auxma 2400K 2835 DC 12V 120LED/m 28.8w/m
2) Auxma 2400K 2835 DC 24V 120LED/m 28.8w/m
3) Auxma 2400K 2835 DC 12V 120LED/m 9.6w/m

The emitters used are the same so the color quality are identical. You choose the voltage and power output. 28.8w/m is much brighter

Alright, I had to ask because there are 3 separate entries in the data. I figured #1 and #2 were the same LEDs. But #3 has a notable drop in it’s R9. It could be the LEDs perform better at higher power.

Good catch. That is possible. The SST20 R9 and CRI values changes significantly with different current levels also

And a big thanks for making this data available on BLF! I placed an order last night for some high-cri led strips. I chose the “Auxma 2700K 2835 DC 12V 120LED/m 9.6w/m” based on your data. I wouldn’t have ventured into the $32 LED strips without your guidance :slight_smile:

Glad you found it helpful. The 2700k has a 103 Rg too so colors will pop.

I guess

and

are related, doesn't it? Which basically means strip #3 uses different, higher value current limiting resistors.

Anyone did some efficiency estimations for led strips? I think it causes a @#$% drop. I would prefer to buy led strips meant to be powered by led drivers, not only efficiency wouldn't suffer but also there would be no distance dimming problems.

I haven’t noticed any distance dimming issues. If you are concerned about efficiency, I suggest you get the 24V strips.

Excellent work.

The Gree LEDs look great value but inconsistent. I have some of their single SMD LEDs and they seem better quality than all other LEDs I’ve ever bought from aliexpress, but I only ever buy cheap junk!

This is great help to me also thank you.
Considering a E27 LED Corn Light Bulb for two car garage light.

Any idea if these are the same Marwalls that were tested here? I just installed some smart dimmers and i’m anxious to get some dimmable LEDs. Don’t have the patience to wait on the slow boat. :stuck_out_tongue:

Nice list, you have been busy!

I might have to try one myself, got some old strips under the kitchen counters that could use some upgrading.

I didn’t know where to put my latest finding…so I put it in here:
5V FOB strip, available in 3000K and 6000K. CRI80.
