In my experience many LED lights last much longer, are brighter, handier, and more durable than the Solitaire. <br><br>I'd look seriously at the Inova micro light. If you need AAA power, there is the ARC AAA, but it's more expensive. The CMG Infinity is similar but uses an AA battery and is thus larger, and the newer ones have a brighter LED. For travel and imposed scarcity scenarios, AA power is a must. <br><br>Once you look at larger lights, LED's advantages stand out less, but still matter in many circumstances. <br><br>Generally, LEDs last much longer than bulbs, both in the life of the element and in battery power. They also maintain their maximum brightness longer. However, overall brightness and range still go to bulbs, esp. high pressure blubs such as in Surefire lights. <br><br>Hope this helps.
