the place you mention sells this one for $34 can anyone explain why at the grow stores its worth the extra 70 most charge to get a hortilux or ushio? I notice alot of grow stores charge $70 or so for ones just like this quality and $100 for the hortilux and ushio

I used to pay $70 for a 170 AgroSun. Then it burned out and I had to replace it with a standard 150 HPS for $20. The garden never knew the difference.

The Eiko lamp is 90,000 lumens, 2100K, 24,000 hours The 100 bulbs lamp is no better but, it is 7 bucks cheaper.

I was looking at 1000 bulbs.com.....does anyone know what the cri number is for after the lumens output?

Edit: nevermind i asked before i googled sorry
