This is an excellent low cost addition to the Mindstorm. By adding to the included light sensor the 2 light sensors can be used to track the front corners or one in the front and one in the back for bidirectional tracking.

I recommend this for one of your first additions to your kit.

Just want everyone to know that it is really true that the price on www. lego.com is much cheaper, it is only $19.99 plus standard shipping charge $6.97. Comparing to it, how expensive here in amazon. same for LEGO Sound sensor $28.99 and LEGO Touch sensor $19.99. So, just go www.lego.com to buy those items and it is really worth it to go there.

well let me begin that saying that i used this light sensor a lot with my team in some competition and for me i love it.
so awesome and really good sensor that detect the light accurately but the processing time it had to detect the light is slow comparing it with the color sensor v2 from Hitechnic .
well we enter it the competition ( following line competition ) and we used the light sensor to compete with other people , and they amazed what this sensor can do with the black line and it was the second fastest robot following the black line after some one who is after then us 0.1 seconds ( just kidding but it was really close to us SOOO CLOSE ) so after all the bottom line of this review this sensor is really good and can detect the light very accurately IMO , and it has low processing speed ( i used the NXT-G programming language to program the robot ) so my advice to you if you dont have enough money to buy the color sensor v2 then you can buy this sensor to detect light and maybe you can detect color too but not very accurately .

The light sensor is an important piece for the LEGO Robotics competitions, but did not come in the NXT kit. We started using and enjoying it with my son's robot right away.
