Industry Is it possible to power a 12V LED bulb using a 5V supply?
Would I be able to power the bulb using the 5V? I''ve bought some boost ic''s that could boost the voltage from 5V to 12V but if I don''t need to use them I''d rather not waste the space. This also means I could dim the bulb using arduino since the supply would be 5V.

To supply 5V modules that sink very high start-up current (like WeMos D1 Mini) put an electrolytic capacitor 100uF/10V on the power rail (in my projects I supply the WeMos D1 Mini by the 3.3V). Why did you make it? I designed the PowerStick to supply power to any solderless-prototyping-boards (breadboards) without power cables.

6 Frequently Asked Questions about “Change solar power supply to 5v mobile power supply”
How do I use a 5V power supply?
Connect the power supply to your circuit and power it up! I personally use the power supply as a tool for basic testing. Usually the 12V side is connected to an Arduino's barrel jack. The 5V output is used for more power hungry loads such as the the RGB LED Matrix or a few meters of addressable (WS2812B, APA102, etc) LEDs.
How do I modify a 12V 5V power supply?
Note: Using screw terminals is one method of modifying the 12V/5V power supply. For a more secure connection, try splicing the wires to a polarized connector and adding heat shrink to your connection. You can also use a USB connector for the 5V side depending on your personal preferences.
How many Watts Does a 9V solar panel use?
This system is for solar panels that are lower than 30W and only 12V only. (9V solar panels would still work). Power used = 15 W Charging time = depends on your solar panel's power and the battery's capacity. USB Output 1 (Buck converter) = 5V USB Output 2 (Boost converter)= 5V
How to convert Li-Po & li-ion battery to 5V?
Switch to Boost converter to convert the battery's voltage 4.2 (3.7 nominal voltage for Li-Po and Li-ion) to again 5V for devices powers 5V. (You can still use the 5V in the Buck Converter during daytime while the Li-Po/Li-ion Battery is charging. It might not be as efficient as the original system (12V).
How much power does a solar panel use?
Power used = 15 W Charging time = depends on your solar panel's power and the battery's capacity. USB Output 1 (Buck converter) = 5V USB Output 2 (Boost converter)= 5V Battery type= depends on your choices (Li-Po/Li-ion) 3.7 and capacity - Mine was Li-Po with a capacity of 3500mAh. One to point:
