Florastar MH 250 Watt
The Florastar MH 250 Watt is a metal halide grow lamp built for the vegetative stage, delivering 25,000 lumens at a colour temperature of 6000 K, noticeably bluer than the 4200 K output of most standard MH bulbs. That cooler spectrum keeps plants short, dense and well-branched before flowering begins. The lamp uses the universal E40 base, runs on any 250 watt magnetic or electronic ballast and offers an average lifespan of 18,000 hours, enough for several full cycles. A straightforward, spec-driven choice for growers who want predictable results from week one. Order the Florastar MH 250 Watt online with fast shipping across Europe.
Florastar MH 250 Watt - 6000 K metal halide grow lamp
The Florastar MH 250 Watt is a 250 watt metal halide (MH) grow lamp producing 25,000 lumens at 6000 K, designed for the vegetative stage of indoor plants. It mounts on an E40 base and ignites on any 250 watt ballast, magnetic or electronic. You will find it in our range of HPS and MH bulbs from 150 to 250 watts.
Engineered for the vegetative stage
Colour temperature is the headline figure here. While most MH bulbs on the market sit around 4200 K, Florastar pushes this lamp to 6000 K, shifting the spectral balance firmly towards blue. Blue wavelengths suppress internode stretching and drive lateral branching, so plants develop into short, sturdy frames with broad foliage, exactly the architecture you want before switching to bloom. The lamp suits vegetables, herbs, ornamentals and fruiting crops alike, from rooted cuttings through to pre-flowering, and performs consistently in grow tents, cabinets and dedicated grow rooms. Because the output stays consistent across the useful life of the bulb, week-to-week comparisons between plants remain meaningful - handy when you are dialling in feeding or training schedules.
Ballast and reflector compatibility
Run the lamp on a 250 watt magnetic ballast (Class 1 or Class 2) or on an electronic unit such as the Lumatek digital ballast 250 watt. One firm rule from the manufacturer: never drive an MH grow bulb in the Super Lumens boost mode found on some electronic ballasts. The E40 screw base fits virtually every horticultural reflector, and when flowering starts you simply swap in a red-spectrum HPS of the same wattage, such as the Sylvania Grolux 250 watt: same ballast, same reflector, different spectrum.
- Blue-weighted spectrum: supports photosynthesis and compact growth from the first week of veg.
- Universal fitment: standard E40 base and 250 watt operation slot into existing setups without adapters.
- Long service life: a high average lifespan spreads the cost over multiple consecutive cycles.
- Simple upgrade path: pairs naturally with a 250 watt HPS for the flowering stage.
Running it right
Keep the photoperiod consistent with a timer; 18 hours on and 6 hours off is the schedule most growers run in veg. Start with the reflector hung high, then lower it gradually while checking canopy temperature: MH lamps generate real heat, so pair the light with adequate extraction. Give fresh cuttings and seedlings a few days to acclimatise before full-power exposure, and log your operating hours, because light output from discharge lamps declines gradually well before failure. Replacing the bulb on schedule keeps results repeatable, cycle after cycle.

Is 250 W enough for a 60 x 60 cm grow tent?
Yes, comfortably. As a rule of thumb, a 250 watt MH covers a footprint of roughly 60 x 60 to 80 x 80 cm, so the Florastar MH 250 Watt delivers strong, even light for a 60 x 60 cm tent throughout the vegetative stage. For larger footprints, step up in wattage or add a second fixture to maintain uniform intensity.
Which ballast does the Florastar MH 250 Watt require?
Any 250 watt ballast: magnetic Class 1 or Class 2, or an electronic model. The only restriction stated by the manufacturer concerns the Super Lumens mode on some electronic ballasts: MH grow bulbs must not be boosted or dimmed through it. At its nominal 250 watts the lamp runs stably and reaches its full rated lifespan.
How long does this grow lamp last?
An average of 18,000 hours according to the manufacturer, which translates to several full cultivation cycles at typical vegetative schedules. In practice it pays to replace discharge lamps preventively, because lumen output declines gradually with operating hours long before the bulb actually fails, and consistent light means consistent plants.
Do you ship this grow light across Europe?
Yes. Orders placed on plantandflower.be are dispatched from Belgium with protective packaging suited to glass bulbs, and delivery is fast across Europe. Your lamp typically arrives within a few working days, ready to screw straight into the reflector.
