I have not used the filament LED, mainly as seen them in Pubs, and could not read the menu. Maybe a special decorative type, but one does need something to defuse the light, a pearl bulb was always better as to a clear glass bulb, never worked out why they were banned.
Looking at this
it seems I can get away with a lower wattage, and since the base of the bulb is at the top. Having a bulb with a plate of LED's inside

will not really matter in this case. I have tried a bulb in a table light at the location, and it could connect to the zigbee hub, I have not tried as yet a socket adaptor, and not really an option to try a switch or relay, as ones I have are not portable, the socket adaptor is more expensive at £10, but will allow me to use the stock of CFL I have in stock, but the smart bulbs at £5 have a screw E27 base, the BA22d base versions are more expensive, the other option is an E27 to SES (E14) converter, as I have some SES smart bulbs in stock, were going cheap in PoundLand.
At the moment, just plugged in while I make up my mind, so looking at the filament type

yes 470 lumens at 3.4 watt, so very economical, but is 470 lumens enough? The 22 watt CFL rated around 1300 lumens, the smart bulb considered is 806 lumens, 8.7 watt and costs £8, but I really don't need colour changing or dimming, but may want dusk setting, not sure if there is a dusk setting with socket adaptor. But first job is testing if it works at that distance.
