What is a good wattage for LED lights?

Buying LED Lighting: The Short Story

LED FLUORESCENT
ANNUAL OPERATING COSTS Low Medium-Low
LIGHT OUTPUT (WATTS/800 LUMENS) 6-8W 13-15W
COLOR TEMPERATURE Varies by product; select high-quality LEDs for consistency Ranges from warm (3,000K) to cool (6,000K)
COLOR RENDERING INDEX (CRI) 80-90+ Most are 60-70+

Which is brighter 2700K or 5000K?

5000 K is “daylight”, which gives a harsher, bright white color tending to blue. 2700 K is good for regular home lighting, while 5000 K is better for office and study spaces or for arts and crafts where accurate color vision is needed.

What is the best LED color temperature?

If you are at home mostly in the evenings, then warmer color temperatures, such as 2700K warm white LED bulbs, are likely the best option. They are more relaxing, less likely to disrupt your sleep patterns and will provide a similar glow to traditional 60 watt incandescent bulbs.

How do you read LED light bulb numbers?

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

  1. A15 bulb: 15/8 = 1-7/8″ diameter.
  2. A19 bulb: 19/8 = 2-3/8″ diameter.
  3. A21 bulb: 21/8 = 2-5/8″ diameter.
  4. A25 bulb: 25/8 = 3-1/8″ diameter.
  5. G11 bulb: 11/8 = 1-3/8″ diameter.
  6. G14 bulb: 14/8 = 1-3/4″ diameter.
  7. G16/G50: 16/8 = 2″ diameter.

How do you calculate LED wattage?

To calculate an LED’s power use, simply multiply the LED’s voltage (in volts) by the LED’s current (in amperes). The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.

What LED wattage for bedroom?

The best light bulb for a bedroom is one that sends out around 800 lumens. This is the same as an older lightbulb (incandescent, not LED) of 60 watts. At 800 lumens, the light will be bright enough to read by but won’t be so bright that it makes you too alert that you’ll have a hard time falling asleep.
