A 1000W HPS lamp is the strongest variant among high-pressure sodium lamps and delivers the highest light intensity for indoor grows. Especially in large grow tents or professional grow rooms, its red-heavy flowering spectrum ensures explosive flower formation and maximum yields. For experienced growers who want to get the most out of their setup, 1000W HPS lamps are the first choice. With the right ventilation, a strong duct fan and a carbon filter, the extra heat generated can also be controlled with ease.
1000W lamps are made for larger grow rooms and tents of roughly 150x150 cm and up, where you need a lot of light over a wide area. This collection includes double-ended HPS lamps from Philips (MASTER GreenPower Xtra 400V) and Platinum, plus a Platinum 1000W DE metal halide lamp for the vegetative phase. Check that your ballast and fixture support DE lamps and the right voltage before ordering. A 1000W setup produces a lot of heat, so plan for strong extraction. See matching reflectors or compare with 600W HPS lamps.
Questions & answers about 1000W HPS Lamps
All growing questions →- Lighting LED or HPS: which grow light is better? LED, for most people with a tent. It's more efficient, makes less heat and the diodes last years. HPS costs less to buy but needs more ve... Read the answer →
- Lighting How many lumens does a grow room need per square metre? None, really. Lumens measure what your eye sees. Plants use PPFD, in µmol/m²/s, so compare lamps on that. Read the answer →
- Lighting How many hours of light do plants need in veg and in flower? Photoperiod plants usually get 18 hours on and 6 off in veg, then 12 on and 12 off to flower. Autoflowering plants can stay on 18/6 or up... Read the answer →
- Problems & pests What is light burn and how do I stop it? Light burn shows as bleached, yellow or crispy leaves at the top, closest to the lamp. Raise the lamp or dim it. Read the answer →
Advantages of 1000W HPS Lamps
Extremely high light intensity: penetrates even dense canopies. Perfect for the flowering phase: red-heavy spectrum for strong flower formation. Maximum yields: ideal for large-scale indoor setups. Compatible with common ballasts & reflectors. Proven technology: the professional standard for decades.
Applications for 1000W HPS
1000W HPS lamps are particularly suited to:
Large grow tents from 150x150 cm upwards. Professional grow rooms with many plants. Hybrid lighting systems combined with LED lamps.
Because of their enormous output, they're less suitable for small tents, as heat buildup and light intensity can quickly become too high there.
Accessories for 1000W HPS Lamps
For a 1000W HPS bulb to be used optimally, the right accessories are essential:
Electronic ballast: for efficient and safe power supply. Large reflectors (Adjust-a-Wings, cooltubes): distribute the light evenly. Extraction systems & duct fans: regulate temperature & humidity. Carbon filters: ensure odor-free exhaust air.
Buy 1000W HPS Lamps
With a 1000W HPS lamp you get the maximum out of your indoor grow. The enormous light output ensures strong plants, dense flower canopies and the highest yields. Whether for large grow tents or professional grow rooms – the 1000W HPS is the ideal choice for ambitious growers who accept no compromises.
