I have a luminary with 12 light points for standard E14 bulbs and a LED dimmer in the wall.
Using Calex bulbs, I only need 6 bulbs, which I run most of the time at 80% light output (measured with the smartphone light meter).
I also tried Toshiba dimmable LED bulbs and I noticed that they produce a different dimming curve. Also, when adding a single Toshiba to 6 Calex bulbs there is incompatibility and all of them flicker alternatively (all the Calex on, Toshiba off, and then the opposite).
As result of the high price of dimmable LED bulbs in general, of the different dimming curves, of the potential incompatibility with mismatched brands and of the not always reliable lifespan estimates (especially with LED "filament" bulbs), I need to ensure that I won't need to replace all of them as soon as one fails.
I see two options: buy some spare bulbs or install more bulbs and run them dimmed further:
- if I install 3 more bulbs I will need to run them at 60% instead of 80% light output, thus reducing the heat load on each one significantly
- if I keep them as spare, I know that I will have compatible bulbs ready.
I am not sure about the advantages and disadvantages beyond the two obvious ones I mentioned. How to choose?
