lux light meter

[jamie419]

Hey guys I have a question about lux. I have a light meter app and it measures lux now I have a 55000 lumen mh bulb and I'm getting around 4000 lux. Is this good. I'm thinking my bulb may be getting weak and I'd like to know if this value is still OK my babies are doing good but I want the best for them any light shed would be appreciated

Best get another bulb and measure both convert to percentage and when the percentage of light coming out is worse than you want replace.

Switched bulbs and things improved greatly. That mh bulb took me through one whole cycle and 3 veg cycles my 2 veg cycles and a warehouse was lit before I got it!
