Which LED bulb size do you require?
The physical dimensions and brightness ratings need to be taken into account when substituting incandescent light bulbs with LED bulbs.
Replace an incandescent bulb with an LED that has the same light output if you wish to increase brightness. But when it comes to conventional bulbs, we're used to measuring brightness by the power rating (in watts). However, as we just said, LED lights are between 70 and 80 percent more efficient than incandescent bulbs. As a consequence, their power consumption, expressed in watts, is much lower. Therefore, it doesn't seem like we are comparing like with like.
Lumens, which are "a measure of the total amount of visible light emitted by a source per unit of time," are often used to describe the output of LED bulbs. Even if it is unfamiliar to us, this is a much higher quality to compare. It is much simpler to evaluate lights that utilize various technologies (incandescent vs. LED, for example) and choose which bulb we want when we don't concentrate on how much electricity a bulb requires (watts).
We've included this helpful "Watts vs Lumens" guide to assist clarify things:
Approximate Lumen Output of an Incandescent Bulb (source: Wikipedia)
250 lumens from 25 watts
450 lumens at 40 watts
800 lumens at 60 watts
1,100 lumens at 75 watts
1,600 lumens from 100 watts
So you should be able to more quickly decide if a certain LED bulb will deliver the same amount of light you anticipate by utilizing this chart.
RV LED lights are directional, which means they only produce light in one direction, which is another issue to take into account. Individual LED bulbs are ideal for spotlights, but panels or rings of LEDs are required to provide ambient illumination that is less focused. Although it may seem bad, this is another another aspect that contributes to LEDs' high energy efficiency.
Light is emitted from a conventional bulb in all directions. In contrast, you want the light to be focused to a surface or an area, not everywhere, in the majority of lighting applications (like a spotlight mounted in your ceiling). The side of the bulb facing away from the surface you're attempting to illuminate wastes the light that it produces.
To attempt to guide the light coming out of the "back" of the bulb in a more beneficial direction, reflectors are included into many fixtures. Even with the reflector, a lot of energy is still being lost. LEDs don't have this issue since they produce light more deliberately. You should make careful to measure the available aperture so you can be sure the new LED bulb will fit. This generally results in the LED bulb/module being a little bigger than the original bulb.
LEDs are also a good option to replace the external lights on your car due to their directed nature.
