The 1.8mm LED has a tip that is 1.8mm across, and below that a square base.

If you are putting LEDs into your project from the inside you do not have to have the whole LED showing to get a nice lighting effect. Use a 5/64 drill bit to have just the small tip of the LED showing.

You can also cover LEDs with plastic lenses. Since they do not get hot you will not have to worry about heat.

Note: We measured several LEDs to arrive at these measurements. We did find some variation among the bulbs that were measured. Please use these measurements as a general guide.

The 3mm LED has a rounded top that acts a little like a focusing lens. If you need more light spread you can sand off the rounded top. Be careful not to sand down to the metal diode inside of the bulb.

If you are putting LEDs into your project from the inside you do not have to have the whole LED showing to get a nice lighting effect. Use a 7/64 drill bit to have just the very tip of the LED showing. You can also cover LEDs with plastic lenses. Since they do not get hot you will not have to worry about heat.

The big difference with the chip LEDs is they get rid of the "legs". These surface mount LEDs have no metal legs extending down. The flat shape makes them very handy for small spaces and flat applications.

The chip LEDs are just great when you need to glue them flat. Like on a ceiling to shine down. Or inside of a street lamp, on the front of a car. Lots of possibilities.

And the brightness is still very good.

Chip LEDs
This Nano chip LED is half the size of our regular chip LED. It still gives a great amount of light, in a tiny package. These surface mount LEDs are also without the "legs". This type of LED has no metal legs extending down. The flat shape makes them very handy for small spaces.

The nano chip LEDs are also great when you need to glue them flat and have very little space. Think inside of a table lamp, on the front small models. Lots of possibilities.

And the brightness is amazingly good for such a tiny LED! Note: We measured several LEDs to arrive at these measurements. We did find some amount of variation among the SMD Chip LEDs that were measured. Please use these measurements as a general guide.

Chip LEDs
This Pico chip LED is half again the size of our Nano chip LED. You have to look closely at the magnet wire to see it. Until you light it up, then you can see it just fine! These surface mount LEDs are also without the "legs". This type of LED has no metal legs extending down. The flat shape makes them very handy for small spaces.

The pico chip LEDs are also great when you need to glue them flat and have very little space. Think inside of a table lamp, on the front small models. Lots of possibilities.

And the brightness is amazingly good for such a tiny LED!

Our brightest LED yet! The mega is a great choice for whole room or whole building lighting.

They are small, compact, and flat for easier mounting. And very very bright! 5mm x 5mm by 2mm thick.

We have taken these SMD Chip style LEDs and taking care with tolerances, added 8 inches of red and green superfine magnet wire.

Get these chips already wired, tested, guaranteed, and fully ready to connect to your power supply. No resistors need to be added, we have done that part if needed!

Mega LEDs
Our largest and brightest LEDs. We have tested larger but have not found many brighter than these.

The 5mm LED has a rounded top that acts a little like a focusing lens. If you need more light spread you can sand off the rounded top. Be careful not to sand down near to the metal diode inside of the bulb.

If you are putting LEDs into your project from the inside you do not have to have the whole LED showing to get a nice lighting effect. Use a 3/16 drill bit to have just the very tip of the LED showing. You can also cover LEDs with plastic lenses. Since they do not get hot you will not have to worry about heat.

If you are getting our AC/DC LEDs for power packs, this is the dimension of our compact rectifier circuit board. The board is only found on AC/DC LED units, located about 3 inches away from the bulb.

Why a rectifier for AC? AC power has switching polarity that will kill an LED. And non-regulated power supplies such as slot car track or model train and doll house power supplies can also damage and kill an LED.

This little circuit will protect your LED for years of trouble-free use!
