LUMii is the value end of UK grow lighting done properly. It is the range most people buy their first ballast or first LED from, and the reason it keeps selling is that the kit works, the pricing is honest and the accessories - timers, contactors, extension leads - are all there when you need them.
- BLACK LED: The BLACK 720W and BLACK2 720/960W full-spectrum LED fixtures for flowering rooms - see all grow room lights.
- Black Blade LED: Bar-style fixtures at 100W (veg), 200W and 400W, plus a 30W UV / Far Red bar for spectrum top-up.
- HPS kits and ballasts: Black 600W digital and magnetic HPS light kits, the 600W digital ballast on its own, and Black HPS dual spectrum 600W lamps. Browse ballasts.
- EnviroGro propagation: T5 propagation lights, the TLED 2ft and 4ft T5 replacement bars and 200W EnviroGro CFL lamps - pair with your propagators.
- Timers and contactors: Black 4-way and 8-way contactor timers and the 26 Amp LUMii contactor timer - see timers and contactors.
- Reflectors: The LUMii AeroTube air-cooled reflector for rooms that need heat pulled straight out.
- Cables and tools: Heavy-duty 1.5m and 5m extension link leads, plus green LED head torches and work lights for checking plants during lights-off.
Why choose LUMii?
It is the sensible first buy. LUMii gear is widely stocked, easy to get spares for, and does not carry a premium for a badge. For a first tent, a veg space or a second room you do not want to spend heavily on, it is hard to beat on value.
LUMii FAQs
Why use a green head torch?
Plants are far less responsive to green light, so a green torch lets you inspect during the dark period without disrupting the photoperiod.
Digital or magnetic ballast?
Digital runs cooler, weighs less and is usually dimmable. Magnetic is cheaper and extremely robust. For most growers digital is the better buy.
Are the TLED bars a direct T5 replacement?
Yes - they are designed to drop into EnviroGro T5 fixtures. Note they are not interchangeable with standard T5 fluorescent tubes in the other direction.
