TP-Link Adds New Color Hub-Free Smart Wi-Fi Bulb

[Julio Urquidi]

The 60 W LB130 is the fourth model released by TP-Link in the past few weeks, joining the LB100, LB110, and LB120.

Like the other TP-Link smart Wi-Fi light bulbs, The LB130 is controlled using the TP-Link Kasa app (iOS and Android); has schedule, timing and countdown settings; and doesn’t require a smart hub. The LB130s can also be controlled individually or in groups, and are Amazon Alexa compatible for voice commands.

The LB130 also gives customers over 16 million colors to choose from, shines from soft white (2500k) to daylight (9000k), and uses an 800lm LED to help reduce energy usage.

Priced at $49.99, the TP-Link LB130 Smart Wi-Fi light bulb is available at Home Depot, and on Amazon.com and the TP-Link website.

One has to ask - TP-Link as a WiFi consumer/AP vendor...

What's the impact to WiFi?

LED lamps do radiate RF based on how the technology works, so many LED vendors have to go thru Part 15 testing in any event...

And most of that RF, because of FCC requirements is pointed at the garbage bands, the 900 MHz, as well as 2.4GHz, as switching power supplies there are very efficient.

With dim-able LED's - it gets even more weird - as dimmers play hell with AC - and this impacts how bulbs like this can offer different light values (colors) and overall brightness.

See below - and this is just for HPAV - there's more sources for interference with LED bulbs in the garbage bands... which impact your wifi...

Be careful what you put in your house as part of the IOT and Green Movements - it can be security and/or RF issues that'll sink your network.

What are those plots of SFX? Conducted, radiated emissions. What are the X and Y axes?

AC ripple vs. time - which ends up being noise on the AC line... more of a challenge with PLC's like HPAV and G.Hn, which is also a concern with any LED lamps (not just TP-Link)...

The chart of interest would be the dimmer chart - that's an old school Thyristor based dimmer for incandescent lamps, and they can raise total heck with PLC's.

The smart LED's like the one at the start of the thread could actually be a benefit since dimming (and other features) are actually inside the bulb, so this could be a win actually.

Wonder if TP-Link could share some things - a light spectrum chart based on some reference colors (LED's can be pretty high in the blue area of the visible light spectrum*), a time-domain noise plot for 50/60Hz, and a noise charts in the HPAV, G.Hn, and 2.4GHz ISM band.

(* some people are pretty sensitive to the high level of blue light in LED's - some of the newer bulbs are better about this than others)

This could be a major win for TP-Link if they're pretty clean in those charts, and getting a strong endorsement from Smallnetbuilder.Com and the SNBForum Hive Mind here could be a very good thing for them.

Conducted emissions is in the FCC test report.

That link requires a log in (possibly). Either way, it doesn't connect (forbidden).

The wifi report looked pretty clean. But I'm still leary of someone breaking in due to some security flaw in the bulb. There's enough trouble with wifi routers and the general security of wifi already. While it would be really fun to have some of these, I think I'll hold off until the security of the IOT matures.

A evaluation about LB120,Maybe it can help you http://www.win-source.net/product-evaluationtp-link-lb120-led-lights
