Is there a summary comparing the different Smart Wi-Fi Light bulbs.  I see 6 models of screw in light bulbs on the TP-Link US site, 4 appear to be multicolored, two are A19/E26, the other two are A60/E27, why would they be shown on the US website? So I compare the TL135E and L535E, Same size/base, lumens, color range, Matter support, et al.  Is this another case of different model numbers for different retailers?

Of the two non multicolor L520E is A60/E27 (220V) but is 4000K (daylight), while the L510E is A19/E26 (120V) and 2700K (Warm White).  Why the difference?  Why is there not a model of each for the each region?

On the Tapo site, which may be global, even more options are listed (L535B, TL13E, L531E, L530B, as well as several spotlight models with GU10 base, and more light strips than listed on TP-Link site. Is that because they are not available in US?

Are there any smart light manufacturers whose products are supported by Tapo app?   It does not look like there are any outdoor or "Christmas" type Tapo lights.
