LED:
    --Uses less energy.
    ^^A single LED uses only 20milliamps, but the higher power ones can require allot more.
    --Lasts longer.
    ^^Most LEDs last 100,000 hours, which is 11.4 years of 24/7 non-stop use, but this can change on voltage environment, other conditions, and even LED types..
    --More directional glow.
    ^^Spread degree of LEDs can vary from 10 degrees to 100 degrees in most cases, but design can correct this problem.
    --More precise colors.
    ^^thousands of colors possible, due to their precise manufacturing abilities of the manufacturers.
    --Tons of colors possible.
    ^^thousands of colors possible, due to their precise manufacturing abilities of the manufacturers.
    --Millions possible with the mixing of RGB LEDs.
    ^^mixing the brightness’ of Red, Green, and Blue can create millions of colors more than the human eye can see.
    --Tons of patterns and effects possible.
    ^^Due to the nature of LEDs, their illumination speeds and color combination can be used to create millions of patterns and effects.
    --Produces no heat, unless high powered LEDs are used.
    ^^nothing about the LED produces heat, but be very cautious with the high powered LEDs because they do produce heat.
    --Can work in any temperature a human can handle.
    ^^the could careless about temperature, but they have their limitations, but we will almost never run into that limitation.
    --Requires minimal voltages, which requires resistors.
    ^^Requires anywhere from 2-4 volts for most LEDs, but there are some that require high voltages. Resistors, or even voltage regulators are required to bring high voltage sources down to the LEDs voltage level.
    --Temper-mental to voltage spikes. A voltage regulator fixes this.
    ^^LEDs can easily be fried by over voltages, resistors are not always good enough to stop voltage spikes, but a voltage regulator does a much better job.
    --Can work on lower than optimal voltages. Mainly for creating other colors through RGB color mixing.
    ^^Mainly for creating other colors through RGB color mixing.
    --Very small in size.
    ^^ Sizes vary from surface mount LEDs, 3mm, 5mm, 8mm, 10mm, and many many more .
    --Mostly waterproof besides contact leads and wires.
    ^^The LED itself is waterproof, but the leads going into the LED casing are not, but a simple coat of many waterproofing agents will fix that.
    --Illuminates in nanoseconds, great for taillights.
    ^^The design of LEDs makes this possible, and if you really want to know why then search the net for more info on LEDs and how they work.


Neons:
    --Brighter than most LEDs.
    ^^but not for long.
    --More even, 360 glow.
    ^^ The design mostly.
    --Colors hard to match with LEDs, and possibly other brands of neons.
    ^^Just the way that manufactures make their neons.
    --Use more energy than LEDs.
    ^^Generally between 1-2amps, but can vary on length of tubes and how many.
    --Only hundreds of colors available, if even that. average around 10-15 colors, but manufactures can have different color hues.
    ^^Manufacturing, and how popular the colors actually are.
    --Produces some heat.
    ^^Design.
    --Requires a transformer.
    ^^The actual Neon elements require very high AC voltage, so the transformer is used to do this.
    --Does not work well with cold temperatures.
    ^^Its mainly the design of the neons, but give it some time and the will eventually warm-up and turn on.
    --Temper-mental to voltage spikes.
    ^^The same as LEDs, the transformers don't like voltage spikes.
    --Temper-mental to almost any voltage variations.
    ^^Under voltage can cause a transformer to burn-out early.
    --Will not last long on lower than standard voltages.
    ^^Under voltage can cause a transformer to burn-out early.
    --Not waterproof, unless specifically said so. Mainly under-glow neons are made waterproof.
    ^^Liquid electrical tape, epoxy, silicone, and many other stuff.
    --Not many patterns or effects possible due to their stupid transformer, which creates a lag time before full illumination.


Cathodes:
Practically the same as neons but
    --Requires a little less energy than regular neons.
    ^^Under voltage can cause a transformer to burn-out early.
    --Are small in size than neons.
    ^^Design.
    --Are generally brighter than neons.
    ^^Design.
    --Are somewhat more fragile than neons, but its all in design.
    ^^Design.



More will be added as I remember them, or a member tells me or even corrects me.
