How much do you want to spend?
You can get an ADA Solar I, Grand Solar I, Grand Solar 250, ATI Sunpower, Maxspect Razor 8k, Radion Pro, etc and all are very nice lights.
Also do you prefer, MH, T5 or LED? Do you want customization? Like dimming, sunrise, sunset etc?
Or do you simply want an affordable light that grows plants with good color rendition?
Any dual T5 should work then.
