> You can make a Dubai Lamp just adding suitable capacitor to the line. Make a low-power Dubai-style lamp from any LED lamp by adding a single capacitor? Surely you must be jesting. Where in the circuit do you propose to add this capacitor to reduce power? How would this differ for a capacitive dropper circuit versus a switching regulator? How practical is this given that most LED bulbs cannot be disassembled non-destructively? Perhaps you are thinking of replacing the current-limiting capacitor in a capacitive dropper lamp with a smaller value: > This is the bit we want to change. At the moment it's a 330 nano Farad capacitor rated at 400V to allow for the peak voltage of our UK 230V supply. I'm going to change it for a 100nF capacitor that will effectively pass less than a third of the current. https://www.bigclive.com/ledlmp.htm https://www.bigclive.com/ledlmp.htm I'd like to point out that this only works in lamps with this design and where the components are accessible for desoldering. You have to do this to a new bulb before it stresses the components, but doing so will void the manufacturer's warranty. Also: > This project involves modifying a mains powered product that was probably built badly in the first place. As such it carries the risk of shock, fire and explosive underpant soiling even when done properly. This kind of design, with an accessible capacitor in a regular PCB, was relatively common in cheap LED lamps 5-10 years ago but things have changed a lot since then. Most modern lamps require destructive disassembly to access these components and have aluminum PCBs that act as heatsinks, making desoldering impractical. However you can sometimes do things like removing one of the current sensing resistors with diagonal cutters to reduce the power: https://www.youtube.com/watch?v=5HTa2jVi_rc https://www.youtube.com/watch?v=5HTa2jVi_rc But the biggest problem with this kind of component-level hack to make a Dubai-style low-power lamp is you now have a light that is significantly dimmer than you started with! I alluded to this when I said the Dubai lamp series tops out at 3 W / 600 lumens when I want a lamp in the 800-880 lumen range. And the 600 lumen Dubai lamp already uses 12 LED filaments, so you'd need something like 16 filaments in a single bulb to approach that 800 lumen range. Where do you propose to find such a lamp?
