I was asked by one fellow who lives in Russia about European lamps. He wants to know what lamps are similar to AgroLite (Philips), Gro-Lux (Osram), Chroma 50/Sun-Shine (GE) Unfortunately, Osram/Sylvania dealer has no clue. The dealer offered him Fluora, Nature, Nature Deluxe (Osram). Can anybody help with these lamps? Thanks, Mike
