LED Question

How does Hobby Kings High Intensity LED Strips compare to the 5050 LED Light Strips? I'm building a Eluminator Flying Wing for Night Flying.

Thanks
Bobby

Hi,

Brightest I have found are 5050's.
I buy the 5050 RGB non waterproof 5 meter
rolls from Ama---.---.

I custom soldered my dozen or so EPP flying
wings for night flying.

By using RGB rolls instead of single color strips
I can cut to length and pick any color I need and
even mix between them since there are connection points
for all three colors and of course positive, 12 volt.

A few mixed colors I use a lot:

Orange is Red and Green with a 330 ohm resistor

Purple is Red and Blue with a 330 ohm resistor

Mostly I use receiver controlled on/off switches and get 12 volt
power from balance plug, 3s battery. I get female balance plug
extension and wire into LED switch and embed this female plug
into the foam next to the flight battery so the male balance plug
from the flight battery just plugs into it.

If you use a receiver switch with a different battery for LEDs
they need common ground wire.

Sometimes I use 4s flight battery but need only 12 volt,
3s for my LEDs, so I use a 4s female balance plug, same as above,
but only wire to 3rd cell wire..... works fine if you
charge your batteries with a balance charger to restore each
cell. Been doing this for 6 months on several flying wings
and batteries are OK.

Sorry for the ramble......back to the question....5050s are the
way to go if you want brightness.

Number_6 Thanks for all the info You answered a lot of my questions I got the 5050 LED Strips, got one meter lengths of Red, White and Blue! I also got a couple of the Female Balance Plug Extension's. I have two of the Eluminator kits. What Wing are you flying? Again, thanks a bunch for the info

I like EPP foam wings for embedding LEDs.

I try to only embed LED strips on bottom of wing....
some facing into the foam to light up the entire wing and
some facing out ....of a different color so I can tell
bottom from top. I also like white on the leading edge only.

As of today I have CrashTestHobby EPP wings.
Grim Reaper model is awesome.

could you run some LEDs off of maybe one AUX port on a receiver, maybe joining two up? read somewhere that a port can give about 6 volts, so maybe joining two up for a 50-100 cm strip, any idea if that will work?

I heard others saying not to pull too much continuous power from receiver channels
so servos are not compromised.

The only things I run directly off the receiver are the "www.flytron.com" Flytron Strobon.
(Strobon SE-strobe-controller board and 2 one watt LEDs)
Just 2 strobe leds, never had a problem with them. Never had
a problem with servos.

For strip LEDs I never use receiver for power for LEDs themselves
they need 12volt.
Get the Turnigy receiver controlled switch #9107000266-0 and the
receiver only has to power the switch...on or off... but the continuous
12volt power for LEDs comes from your 3cell battery.

You can run several of these switches from spare receiver channels, I have many times.

I rig up a female balance plug near the battery so just plug battery balance plug
into it....pull power (+) from third cell (12 volt) only, and ground (-). These
feed the strip LEDs .... the red (+) wires from above switch just wire into
the power wire and the receiver channel is setup as a switch on your
transmitter....so as I said the receiver switch just turns on the power
from your 12 volt battery to the strip LEDs

I use Strobons receiver power from bind plug after binding of course...

Example on my flying wings: I use switch for all embedded LED strips from
a switch on rudder channel... my wings use elevons only so rudder channel
makes a good switch location.

My second switch runs on gear channel and controls 4 three watt Eagle Eye headlights
embedded in LE.

BTW all these LEDs use very little power, surprising how little.

One last thing...most of my new builds are 4cell so I only grab power from 3rd cell
on the balance plug.... very important here... don't pull more than 12 volts for strip LEDs
or burn out.

Note: this is all custom wiring/soldering and I don't use 'kits' for any of this...if this doesn't make sense
to anyone please don't try it. Disclaimer...this is general info that works for me and I don't
mind sharing but I am not responsible for your project. Test and test again.


Here's a recent dusk flying video with lights setup as described above.

I saw some 5730 LED's on Amazon, supposed to be brighter than 5050's, haven't tried them though.

Thanks for the tip, ordered a roll of non-waterproof 5730 to try out.

Received the 5730 LED roll.
They are bright but get hotter than
5050's.
So, I need to test them
embedded in scrap foam
before I use them in a foam
flying wing.
