SKV89's LED Strips and bulbs test results

EDIT: Thanks to member Sac02 for organizing my data into a user-friendly spreadsheet in this link.

I tested most of these half a year ago but was going to post them after I have time to put them in an easy to read table but given my current real world commitments, I doubt I’ll have time to do that anytime soon so I decided to just post what I have. It will be a long post.

My purpose for testing these is to find the best lights for use in my home. I like warm lights with negative DUV (below the BBL or rosy tint) with very little blue light to minimize suppression of melatonin. My favorite so far is the Auxma 2400K led strips with the SMD2835 due to their perfect warm cozy rosy tint and very low blue light content. Overall, I’ve been very surprised how high the light quality is in almost all of these Aliexpress/Alibaba lights I’ve tried. Compared to the dozen or so different led strips I bought from Amazon 5-6 years ago that tested 60-70CRI with positive DUV (green tint), these are in a whole nother league. I just wish high powered LED for flashlights will match these in light quality in the near future.

Very helpful. Just edited, fixed and decrapped the links in your opening post, SKV89. Edit, copy and paste the content below for the way the Lord likes it, please. I'll remove this redundancy then:

Done

Please avoid quoting lenghty posts, namely with nested quotes. Trim the quote down to the essential. Helps with forum neatness and legibility. Thanks.

Sharing localized AliExpress links is bad: when a user clicks or taps on a localized link their system automatically sets that locale, most often forcing the user to tap or click on the locale drop down or global site link to return to their localized site of choice or to the global site. Your carelessness is thus detrimental. I understand AliExpress should fix their site behaviour, but while this happens please be mindful and only share global website (english) links. Turning a localized link into a global link is super easy, just change the locale letters in the url for wwwExample:

Thanks Barkuti for fixing the links. I copied it into the OP.

xevious, I’ve bought several different power supplies. Make sure you get UL listed ones. They are a little bit pricier but worth the extra for the protection. Here is a list of websites that I think have trustworthy power supplies.

This the 24v powersupply that I’m using
I can’t remember which 12v I got but it is UL listed.

There are some issues, still. It has to do with limitations of the simple post editor, I think; you could switch to the advanced editor and then paste my edited content, it will straight work then.

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+. Smile

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

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.

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 Smile

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

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.

Sharing localized AliExpress links is bad: when a user clicks or taps on a localized link their system automatically sets that locale, most often forcing the user to tap or click on the locale drop down or global site link to return to their localized site of choice or to the global site. Your carelessness is thus detrimental. I understand AliExpress should fix their site behaviour, but while this happens please be mindful and only share global website (english) links. Turning a localized link into a global link is super easy, just change the locale letters in the url for wwwExample:

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.

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. Silly

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.

Wow, that’s a lot of research there.
Some amazing specs among those strips.

Indeed, the high power LED manufacturers could perhaps learn a thing or 2 from this.

Thanks for doing this. Thumbs Up

Great list!

I wish I had access to this before redoing my kitchen. I used Flexfire LED Strips and the DUV is def positive.

Thank you for doing all the work and recommending Auxma strips. I have purchased 2400K 3000K and 5000K rolls. Awesome light quality.

Anyone did some efficiency estimations for led strips?

For the 24V 3000K strip, resistors are 56 ohms.

At the beginning of the strip, close to the power supply connector, there is a 3.46V drop on the resistor so LED current is 62mA.

3.46V is 14.4% of 24V so resistors waste 14.4% of total power, and LEDs get 85.6% of total power. Not so bad.

At the end of the 5m strip, 2.7V on the resistor, so only 48mA LED current. Thus 5m is a bit too long for a single power connection.

Note efficiency depends on LED color. For 24V having six white LEDs in series is okay, it wastes only a few volts in the resistor. But manufacturers use the same PCBs for all colors! So RED strips, with much lower Vf LEDs like 1.8-2V, will waste like 50% of the total power in the resistors… Not good!

Thanks for the data bobflux.

The efficiency loss is a bit of a problem atop of the uneven brightness thing caused by the uneven distance to the power supply which each strip stage has. It is a cheap and simple way to have led lighting, but far from being the best. I'd rather prefer strips in series (without resistors) powered by standard (usually AC powered) led drivers; this requires good isolation and limits concerning minimum and maximum strip lenght, though.

I’d say “it depends”.

A 10W light (about 1000 lumen) which is on 4 hours a day will use 14 kWh per year or about €2.20 of electricity every year.

Replacing incandescent lights with LEDs really saves energy and money. But optimizing LED efficiency beyond 100 lm/W isn’t really interesting IMO, it gets into diminishing returns. I’m willing to trade some efficiency for better color rendering, better look and aesthetics… but modern LEDs, even the high CRI ones, are already very efficient, so the energy cost isn’t that much anyway.

Bottomline, lowering the heating thermostat by 0.1°C will probably be unnoticeable and save much more energy than optimizing LEDs…

Meh, bypass the resistors with solder blobs and use a real driver for the lengths you cut yourself.
