Hey mate,
If you wanna stick to a 1lamp setup, you maybe also check Viparspectra KS-Series. I know, its not the brand you first wanted, but most other LEDs have a rather uneven light distribution and imo suck as a single lamp setup.
marshydro also has a similar model to yours, that is cheaper and more liked by the community.
Otherwise if u wanna stick to SF, go with the G model its better for your elecricity bill and just a newer model of the brand, so probably some other upgardes aswell
