To Start, Lets Talk About What These 3 Number Codes Mean When Applied To LED Chips Types.

LED LED and () LED are the 3 most commonly used surface mount diodes for flex strip lighting. They are traditionally used in mono-lights or RGB flex LED strip lighting.(aff.) As LED technology advances, these 3 types of LED chip are now used for home and commercial lighting to replace compact fluorescent and other incandescent lighting.

 
Once you see the 3 types of diodes, you can easily tell that the LED is smaller in size than the LED. But what most people do not know is this , a LED actually contains 3 sets of LED chips inside. So a LED is actual a combination of 3x chips in 1.

The () LED is basically a stretched LED with a much wider viewing angle. Making the () LED the brightest of all 3 with the lowest power consumption per watts. The wider angle makes it easy to emit a brighter output with the same wattage.

A LED will illuminate brightness equivalent to approximately 6 Lumen

A  LED diode will illuminate brightness equivalent to approximately 18 Lumen

A  () LED diode will illuminate brightness equivalent to approximately 50 Lumen

The same goes for each chip's power consumption, a LED will consume approximately 0.06 Watt, while a LED will consume approximately 0.18 Watt of power and a () consumes about 0.5 Watt.

Some Data For Your Tech Heads

LED Dimensions Chip Surface Area Lumen Flux Power Draw LED 3.5 mm x 2.8 mm 9.8 mm² 6-8 lumens 20-30 mA @ 2.8-3.4 Volts LED 5.0 mm x 5.0 mm 25 mm² 16-22 lumens 60 mA @ 2.8-3.4 Volts () LED 5.6 mm x 3.0 mm 16.8 mm² 45-50 lumens 150 mA @ 2.8-3.4 Volts

 

Keep in mind that different diodes with different countries of origin will deliver different results. The above data is for reference only.

Here are some of the different variations of each of the 3 (, , / ) types of 

LED

 in action. The variations are endless.

LED cluster in a G4 tower JC halogen light bulb replacements - wide voltage range of 10 volt to 30 volt, making them optimal for systems with a fluctuating voltage range. LED cluster bayonet BC B22twist and lock fitting - wide voltage range of 12V - 18V and suitable for off grid solar panel battery and marine boat systems.

LED cluster MR11 spot lights in GU4.0 2 pin fittings - input voltage is DC 12 volt to 14 volts and easy replacements for any home halogen spot lights to save big on heat and power.

 

 

 

 

They aren't 'types', they are sizes. What you are asking is like asking whether jumbo eggs are better than medium. The size doesn't tell you anything about the taste. That would be determined by the chicken, what it was fed, and how the egg has been handled. Luminous efficacy is unrelated to the package size, unless the package is too small to handle the heat. It is related to the die that is put in the package, and the material that's put over the die. These vary between brands and models, not size.

I suspect the answer to your question is that the package technology has changed enough that the smaller package can now handle the power, so the larger packages are no longer needed.
