Halogen Bulbs
Yes, LEDs are dimmable.
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.
LEDs come in different types based on how they’re used. The most common ones are: Miniature LEDs – Used in remote controls, indicators, toys High-Power LEDs – Bright and long-lasting, used in industrial lights RGB LEDs – Change colors, great for displays and mood lighting SMD LEDs – Found in strip lights, TVs, and flat panels COB LEDs – Give strong, focused light, perfect for spotlights and studio setups Bi-color & Tri-color LEDs – Offer multiple colors in one unit If you’re looking for professional lighting—like for film, photo, or ad shoots—brands like Godox and Aputure offer solid options.
