@iceuhaw

Meron po nabibili nyan sa rscomponents or sa farnell yata, dko ko pa na check din kasi.
Etong ginamit ko dito e free sample po ito galing maxim, mga two years ago na yata to sa akin. Ngaun ko
lng napagtripan gawan ng pcb at tinesting....hehe

at medyo mahal pa ang mga HB leds noon...

@Woots29

pwedeng pwede ito sa headlights ng mga sasakyan or sa mga motor. kaso kelangan mo ng at least 12 to 15w ng LED (5 x 3w na HB led ) para mahigitan mo ang liwanag ng 55w na halogen or 35w na HID.

balak ko nga sana gumawa ng headlight para sa motor na LED ang gamit.
pag na testing ko na. i post ko dito...

ung project ko kasi ngaun e gusto kong palitan ng leds ung  mga ilaw sa mga Downlight fixtures...

bale pang house lighting na LED...
