What brand of light bulbs last the longest?
LED Bulbs. LEDs usually have the longest lifespan, often lasting over a decade. Mostly, they are several times better than incandescent bulbs and most fluorescent bulbs.
What does A15 mean on a light bulb?
Another common A-series light bulb type is the A15 bulb which is commonly used in the US for appliances and ceiling fans. The A15 bulb is 15⁄8 in (1 7⁄8 in; 48 mm) wide at its widest point and 3.39 inches tall.

Which is brighter LED or CFL?
LED VS CFL Brightness In short, LED and CFL as technologies do not have a difference in brightness intrinsically. Brightness is determined by lumens. A single CFL and LED bulb might have the same lumen (brightness) output but vary greatly in the amount energy needed to generate that level of brightness.
Can I use an LED bulb in a CFL fixture?
While LED lighting used in enclosed fixtures may bring up some potential heating problems, this is nothing compared to the energy inefficiency of CFLs and incandescent light bulbs. Unfortunately, due to the heat entrapment of enclosed fixtures, not all LED light bulbs can be used.
Can I put an LED bulb in any lamp?
LEDs can be used in any light fixture, as long as it’s not enclosed or air-tight, and is not an old-style dimmer system. Both these will shorten the lifespan of LED bulbs.
Why are LED lights not suitable for enclosed fixtures?
Heat is the enemy of LED light bulbs. Enclosed fixtures that don’t allow for proper ventilation can drastically affect the temperature of the LED bulb, causing it to overheat and shortening the lifespan of the bulb. …
Can I put LED bulbs in halogen fittings?
ANSWER: Yes, there are LED bulbs you can use in your fixtures. The LED equivalent to the 50-watt halogen bulb will probably burn only about six or seven watts. These LED bulbs cost more, $30 to $35, but because they will last for years, they are worth the price. And LEDs give off relatively no heat at all.
How do you convert a halogen bulb to LED?

Can I replace 12v G4 halogen with LED?
#3 The compatibility While replacing 12v halogen lights with G4 LED 12v, it is important to check the compatibility of the G4 LED lights with the lighting fixtures. As mentioned before, most of the G4 LEDs operate on DC voltage, so they will need a different power supply or transformer to operate.
Can I replace MR11 halogen with LED?
I’ve seen MR16 LED retrofit lamps, are LED lamps also available to replace the smaller MR11 halogen lamps? Yes, LED versions of the 35mm diameter M11 lamps are available in both non-dimmable and dimmable versions, with light outputs generally matching the original 20W tungsten halogen lamps.
How much does it cost to replace halogen downlights with LED lights?
Some electricians may charge as much as $100 per downlight, but expect to be charged around $60 – $75 per point for installing LED downlights.
What is 20W halogen equivalent to in LED?

Do I need a special transformer for LED lights?
All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally.
What is the difference between a transformer and an LED driver?
LED drivers and electronic transformers for retrofit LED lighting are not interchangeable. They differ in output and load compatibility i.e. which LED lights they will work with. The fundamental difference between the two is that LED drivers output DC while electronic halogen transformers output 12VAC.
Do LED bulbs run on AC or DC?
In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. Lynk Labs has developed technology that allows LEDs to be driven directly from an AC supply. LEDs are usually considered to be DC devices, operating from a few volts of direct current.
What are drivers for LED lights?
LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for low- voltage bulbs: they provide LEDs with the electricity they require to function and perform at their best.
Do LEDs need constant current?
Just because LEDs are constant current devices doesn’t mean that they require a constant current power supply. In some cases, constant voltage power supplies might be best. We compare constant current LED drivers and constant voltage LED drivers to help you pick the perfect LED power supply for your application.
How do I choose an LED driver?
Use an LED driver with at least the same value as your LED(s). The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span.
What wattage LED driver do I need?
We recommend choosing a driver with a wattage capability at least 10% higher than the wattage the LED tape requires to ensure a longer lifespan. For example, 5m of 6w LED tape requires 30 watts. We would recommend using a driver with an output capability of 33 watts or more to power this tape.
How much power can an LED handle?
The LED current must be less than the maximum permitted for your LED. For standard 5mm diameter LEDs the maximum current is usually 20mA, so 10mA or 15mA are suitable values for many circuits. The current must be in amps (A) for the calculation, to convert from mA to A divide the current in mA by 1000.
How many amps does a 12V LED use?
10 Amps
How do I know what size LED transformer I need?
Take the length of your LED strip in feet and multiply it by the watts consumed per foot, then multiply by 1.2. This will give you the minimum sized power supply you’ll need to run your strips.
How many lights can you put on a 300 watt transformer?
(8 lights X 20 watts = 160 watts). If you want to connect ten landscape lights to a magnetic transformer, and the lights use 30 watts each, you would need a 375 watt transformer. (10 lights X 30 watts = 300 watts, and 300 is 80% of 375).
Do LED lights attract bugs?
Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.
How many feet of LED lights do I need for my room?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
