Hey all, apologies for delayed response here. Randy, appreciate the feedback there, and agree on all points. Wayne, Hardware V2.0, firmware 1.1.0 b230721 rel. 224802 As mentioned, anything above 50% on the two tapos is audible as a high pitched whine. I’ve ordered some more from Amazon and will write back when I test them (eta early December)

  @Mully_DE Hopefully you'll get some good ones. Use a dB meter app to identify the quietest out of the pack.

  @RandyAndy Update and results below

 

Tests done with 2500k white. Peak level, 10s test, Umik measurement mic on a stand. Same distance (20 cm).

 

2x V2 Bulbs (Only saved one results, my bad, but identical result).

3x V3 Bulbs

 

V2 @ 100% significant noise 900hz with overtones at 1k and 1,1k

V3 @ 100% no additional noise except for minor imperceptible peak on only one of the bulbs @ 1,1k

 

Download REW and see the measurements here: https://drive.google.com/drive/folders/16jtBS6h-SCtYE3x43GeZD19M2MRjMRpL?usp=share_link

 

My conclusion. V3 fixes a manufacturing error with V2. Replace all V2 for V3, test, rinse repeat till you're happy :)

  @Mully_DE Thanks for the detailed tests. So did you buy all those bulbs at the same time, or the v2 ones first and then the v3 after some time? Are you in the EU (from your forum user name I had assumed you are in Germany). If so maybe I'm in luck, as a lot of imported stuff comes through Germany (I'm in Spain). I'm just trying to figure whether I'll receive v2s or v3s if I buy mor L530E bulbs now. Although your test sample is very small and we cannot be 100% sure they have fixed it, I want to believe that is the case. I might just pull the trigger and buy a couple more to see if they I get v3 bulbs.

 

Perhaps TP-Link/Tapo personnel could confirm the difference between v2 and v3? If the noise has officially been fixed, that would give me confidence to purchase (and recommend) this product.

V2’s purchased last year. V3’s purchased this month. Amazon.de and on the v3 box it has a shipping address from TP-Link Germany. V2’s no clue sorry So, I think buying from Amazon.de should be a safe bet :)
