Run them less than 50% it should last somewhere between 50,000-120,000 hours so I'm not sure where that idea came fromLike I said if they did not lose efficiency so fast and the cost was lower for a bulb and the heat output was less and....yeah there's that height above canopy thing as well....It might be worth it...
The costs in electric, cooling, and replacing favor Cobs by a long way and newer Cob tech is already on the way.
If you have lots of headroom and $ to spend and want something you can just slap up and grow, regular light bulbs would be an option.
