the 3w rgb leds are $1.30 each so that takes up the bulk of the price. the led is on a 20mm heatsink, and i can fit the electronics inside a 30mm plastic dome.
as far as placing these in series, i'll still need close to a 5watt resistor.
interestingly enough, all 3 colors use the same 27 ohm, 5 watt resistor. (the red is lower voltage, but uses more current)
Reminds me of the led used on aethers. Perhaps you can call them aether strobes.
the aether's led is bigger in size (and in the current it uses)
i think the aether's is about 28mm
this one is 20mm
Hi,
5W resisors are big and you'll need 3 in each strobe. How do you plan on placing these in your design?
Have you considered using 2 or 3 RGB LEDS in series to lower the voltage across the resistors?

there is plenty of space in the plastic dome to fit everything. I left the led cycling for about 30minutes, nothing got hot. nothing even got warm.
What about heat issues? or will the random firing ofset that.
by using 5watt resistor (which is well over the 3 to 4watts thats needed) there isn't an issue with any of the components getting warm.
