What does COB mean in LED?
Chip on Board
COB, or Chip on Board is a fairly new member of the LED family. Multi LED chips are packed closley together as one lighting module. And when it light up, it appears like more of a lighting panel than multiple individual lights if that makes sense.
What is difference LED and COB?
Like the SMD, COB chips also have multiple diodes on the same surface. But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have nine or more diodes. COB chips also only have one circuit and two contacts, regardless of the number of the diodes.
What is 18w in LED?
LED equivalents to fluorescent tube lights
| Fluorescent Tube Light Wattage | LED Equivalent Wattage |
|---|---|
| 70 Watt | 24 Watt |
| 58 Watt | 22 Watt |
| 35 Watt | 18 Watt |
| 20 Watt | 9 Watt |
What is 18W size?
In many cases, a women’s size is roughly equivalent to the next misses’ size up. For example, an 18W is similar to a misses’ size 20.
Are COB lights any good?
While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB LEDs are a single-point light source (meaning all light comes from a single point in space).
What is an 18 watt bulb equivalent to?

These clothing lines are often made for those with more generous curves and may have more ample bust and hip areas, too.
How many watts COB LED?
COB (chip-on-board) or Integrated LED lighting is simply printed circuit boards with many low-wattage diodes directly mounted. For example, a “50W” COB LED may be comprised of 50 1W diodes, or 100 0.5W diodes.
How many lumens is 18 watts?
Wattage to Brightness Comparison
| Incandescent Bulb Wattage | Equivalent Halogen Bulb Wattage | Equivalent CFL Bulb Wattage |
|---|---|---|
| 40 W (~460 lm) | 28 W | 7 W |
| 60 W (~830 lm) | 45 W | 13 W |
| 75 W (~1100 lm) | 56 W | 18 W |

What is size 18W equivalent to?
What does 18W mean in size?
plus size
Numerical sizes are often labeled as 14W, 16W, 18W, and so on. The W is for Women’s, which is another way of saying plus size. The “W” sizes are fitted for plus size specifically, whereas sizes like 14 and 16 in the same brand were likely fitted on a straight-size fit model.
