Ai có ng` thân bên mỹ nhờ mua dùm mí thứ này ship vìa Vn mà xài,rẻ hơn đồ ADA nhìuI haven't built one of these yet, but it's almost the same as what I did build in this thread: $70 DIY 70W HQI Metal Halide The only difference is a more efficient and better looking reflector, and more power.
$49.99 BallastWise.com 150W eballast HID E-B DXE150HID1
$20.20 Astralux MH 150W DE 8KK Ultra White Bulb
$29.95 Reflector and Sockets from HelloLights.com
Grounded power cord, and a couple wire nuts (you probably already have, if not a couple bucks).
~$100 plus shipping for a complete 150W retro, and the reflector looks awesome. 67 cents a watt! Plus, for $65 more you could get the ADA 8,000k bulb.
