From the LED lights forth are okay, but not quite as bright as 20 watt halogen. The bigger problem is that in the version hold the LED poorly and often fall out. Here it is already broken one. I can recommend you only conditionally, not because of the brightness, but because you keep just bad and fall out and down.
Addendum 01.01.2014:
These LED are junk! Stay away and fire hazard! Meanwhile, all broken, never again!
