LEDs - I used 5mm LEDs. You can change the type of LEDs as long as you augment the calculations accordingly.
Bridge Rectifier - Converts AC to DC.
Perfboard - The size of perfboard you buy will depend on the size of light bulb you wish to create.
Soldering Iron and Accessories - The cheapest of soldering irons will do.
Base Plug - This product has a normal bulb's base at one end and a normal household outlet on the other. Your local hardware store will most definitely have some.
Cable Ties - The question here is not if you have them, but, rather, how many hundred of them do you have.
Cardboard - This is the main support piece for all the component of the bulb.
Wax Paper - I used a silicon cookie sheet (that rolled up blue thing) instead. You can use practically anything that has a high temperature tolerance and doesn't conduct electricity, but I have found these to be the best materials for the job.
Drill and Small Bit - I used a 1/8" drill bit.
X-ACTO Knife and Whole Puncher - These items will be used to prep the insulation.
20AWG Wire and PVC Pipe - These are required to connect the bulb's base to the rest of the assembly.
Multimeter - I always keep my multimeter handy in order to check conductivity and make sure there are no shorts.

Long story short: yes, and for the most part I would recommend it, especially if you go with 12v you could easily convert it to an off grid solar project as well, since smaller projects like that stick with 12v.
Everything I found so far is for low voltage, don't know if it would be as simple as slapping in the Mosfet in series with the LEDs.
I used 5 mm Ultra Bright White LEDS. VF is in the range of 3.4 Volts to 3.6 Volts. The Hydro here, is in the range of 115 +/- 5 Volts AC 60 Hz. It's the Country, things go up and down. The Math given did not account for numbers on the other side of the decimal point. So 46.05263 was rounded off to 46 LEDS for a Voltage of 125 Volts AC or 175 Volts DC..
Using the Math given 120 Volts X 1.4 = 168 Volts DC.
168 Volts DC/3.6 VF Max = 46.6666 # LEDS Do we round off to 47 or leave it at 46?
Check
110 X 1.4 = 154 Volts DC
154 Volts DC/47 # LEDS = 3.27 Volts this is lower than 3.4 Volts VF Min.
The AC Voltage range it will work in is then:
47 # LEDS x 3.4 VF Min = 159.79 Volts DC/1.4 = 114.14 Volts AC Min
47 # LEDS x 3.6 VF MAX = 169.2 Volts DC/1.4 = 120.857 Volts AC Max
this is a 6.717 Volts AC Variation.
I used 46 LEDS
46 # LEDS x 3.4 VF Min = 156.4 Volts DC/1.4 = 111.7 Volts AC Min
46 # LEDS x 3.6 VF Max = 165.6 Volts DC/1.4 = 118.28 Volts AC Max
I made 9 all the same type with 46 LEDS in series, powered by a Bridge Rectifier. No Epoxy this time. 2 failed after 2 seconds of power on. The rest worked Ok so far.
I'll monitor the line voltage, for maximum and minimum spikes for a while, see what the AC voltage variation actually is. Might have to fix this with a resistor, or more LEDS or something??

I'm not trying to be negative, and I hope with some explanation I won't be "kept in the dark" for any longer...
