| Lighting Science Group Launches Ultra-Efficient European Line of DEFINITY LED Bulbs
 
 Europeans Now Have the Freedom of Saving Green by Buying Green Without
 Sacrificing Lighting Quality
 
 SATELLITE BEACH, Fla., April 14, 2011 /PRNewswire via COMTEX/ -- Leading the
 ultra-efficient lighting revolution - Lighting Science Group (LSCG) today
 launched a European line of its DEFINITY LED bulbs that have a higher lumen
 (light) output than many of its competing products at a dramatically lower retail
 price. Europeans can now start lowering energy cost without sacrificing light
 quality by installing Lighting Science Group's DEFINITY line of LED light bulbs.
 The line includes MR16, PAR38, R63, R95, G80, and A60 bulb types that are
 approximately 80% more efficient than traditional incandescent bulbs, are
 dimmable and will last nearly 25,000 hours (25 times as long as a typical
 incandescent bulb).
 
 "Our European DEFINITY line of LED bulbs sets a new standard for lighting
 performance at an affordable price," said Rich Weinberg, chairman and chief
 executive officer of Lighting Science Group. "These bulbs offer the best lumens
 per dollar and can save users hundreds of dollars in maintenance, replacement and
 energy costs. Furthermore, unlike CFLs, the DEFINITY LED bulbs contain no
 mercury, are completely recyclable, are 'instant on,' and offer outstanding light
 quality."
 
 To ensure performance and reliability, the DEFINITY LED line was tested under the
 rigorous LM-79 process by an independent laboratory approved by the U.S.
 Department of Energy's CALiPER program. These testing results show that the
 DEFINITY LED bulbs outperform many competing products on the market. Moreover,
 saving green by buying green has been made easier, since the DEFINITY LED bulbs
 have a payback of one to two years.
 
 "With the phase-out of incandescent light bulbs, Europeans can now purchase
 long-lasting, environmentally responsible and sustainable replacements that make
 economic sense-without sacrificing lighting quality," added Weinberg.
 
 The DEFINITY line of LED light bulbs is being offered through lighting
 distributors and directly by Lighting Science Group. To find your nearest sales
