led lights may be good in the future,,,but as of now they are still trying to get it all wright.. an led now will not produce like an hid period! however led is good to use along with your hid,, but alone an led can not even compete.. tests have shown led produces shorter plants and stresses out trics..i called bc northern lights and asked why none of there boxs contain led...because hids are plain out better and they have won numerouse gear of the year awards i think for the last 8or 9 years now...believe me, i want to go led, to save well needed cash, but ill wait,,wait, and wait some more untill leds are a stable.. wright now u buy one and need a new one in a year or 2, they will keep improving,, waste of money like buying a projector tv wen the hi defs come out the next year..the fact is led is good for added lighting not stand alone..i do believe led will be the light,, but in the future,,,not yet..
