What does dual spectrum mean?
A dual spectrum lamp combines the strong red-rich output associated with HPS lighting with additional blue light, creating a broader spectrum suitable for more than one stage of plant development.

The Loadstar 250W Dual Spectrum Lamp is a high-pressure sodium plant lamp designed to provide a broader spectrum for both vegetative growth and flowering, making it a versatile choice for smaller HID lighting systems.
Unlike a conventional flowering-focused HPS lamp, a dual spectrum lamp supplements the strong red and orange output associated with sodium lighting with additional light in the blue region of the spectrum. This creates a more balanced output for use across multiple stages of plant development.
At 250W, the Loadstar offers a lower-power alternative to larger 400W and 600W HID systems. It is particularly useful where a compact lighting footprint is required or where the heat and power consumption of a larger HID lamp would be unnecessary.
The lamp requires a compatible 250W ballast and suitable HID reflector. It is not a self-ballasted lamp and must not be connected directly to the mains supply.
Why choose the Loadstar 250W Dual Spectrum Lamp?
- 250W dual spectrum lamp - designed for smaller HID plant-lighting systems.
- Suitable for growth and flowering - broader spectral output allows one lamp to be used across different crop stages.
- Red-rich HPS output - provides the strong red and orange wavelengths associated with flowering and fruiting.
- Additional blue output - improves suitability for vegetative plant development compared with a flowering-focused HPS lamp.
- Full-cycle flexibility - reduces the need to swap between separate vegetative and flowering lamps.
- Lower-power HID option - useful where a 400W, 600W or 1000W lighting system would be unnecessarily powerful.
- Compact lighting applications - well suited to smaller crop areas and supplementary lighting.
- Compatible with appropriate 250W control gear - can be paired with a suitable 250W HPS or dual-spectrum ballast and reflector system.
Dual spectrum light for vegetative growth & flowering
Traditional high-pressure sodium lamps are particularly strong in the red, orange and yellow regions of the spectrum. This makes them highly effective during flowering and fruiting, but less balanced than some other light sources for vegetative development.
The Loadstar Dual Spectrum lamp broadens this output by providing additional blue light alongside the characteristic red-rich HPS spectrum.
The result is a more versatile lamp that can remain in use as plants move from vegetative development into flowering, rather than requiring a separate metal halide or blue-spectrum lamp for the earlier growth stage.
Where is a 250W dual spectrum lamp useful?
A 250W HID system occupies a useful position between lower-output propagation lighting and substantially more powerful 400W, 600W and 1000W systems.
- Vegetative plant development - additional blue-spectrum output supports use during active foliage and structural growth.
- Flowering and fruiting - the strong red-rich HPS component makes the lamp particularly useful during reproductive growth.
- Full-cycle lighting - one compatible lamp can remain in use across multiple crop stages.
- Smaller crop areas - 250W can be more appropriate where the intensity and heat of a larger HID installation are not required.
- Supplementary lighting - can be incorporated where additional mixed-spectrum illumination is required.
Requires a compatible 250W ballast
The Loadstar 250W Dual Spectrum Lamp is an HID discharge lamp and therefore requires suitable control gear to start the lamp and regulate its electrical operation.
A compatible 250W ballast must be installed between the mains supply and lamp. The lamp must not be connected directly to the mains.
Loadstar produces a 250W magnetic ballast, while suitable multi-wattage digital ballasts may also support 250W sodium and dual spectrum lamps. Always confirm compatibility with the specific ballast before installation.
Pair with a suitable HID reflector
The reflector has a major influence on how effectively the lamp's output is distributed across the crop. A suitable reflector directs light that would otherwise travel upwards or sideways back towards the plant canopy.
Reflector shape, mounting height and positioning all affect the resulting lighting footprint. For the most uniform coverage, position the fixture centrally over the intended area and adjust its height according to crop response and environmental conditions.
Heat management & lamp positioning
Although a 250W HPS lamp produces less heat than higher-powered HID lamps, it still operates at a very high temperature and requires appropriate ventilation and clearance.
Lamp-to-canopy distance should be selected according to the reflector, environmental temperature, crop stage and plant response. Avoid positioning the lamp so close that foliage experiences excessive heat or light stress.
The lamp and reflector become extremely hot during operation. Always switch off the ballast and allow the system to cool fully before handling or carrying out maintenance.

Loadstar 250W Dual Spectrum Lamp FAQs
Can the Loadstar 250W Dual Spectrum Lamp be used for vegetative growth?
Yes. The additional blue component makes a dual spectrum lamp more suitable for vegetative development than a conventional flowering-focused HPS lamp.
Is the lamp suitable for flowering?
Yes. The lamp retains the strong red, orange and yellow output characteristic of HPS technology, making flowering and fruiting key applications.
Does this lamp need a separate ballast?
Yes. The Loadstar 250W Dual Spectrum Lamp requires compatible 250W control gear. It is not self-ballasted and must not be connected directly to the mains supply.
Can it be used with a digital ballast?
Yes, provided the digital ballast is specifically compatible with 250W sodium or dual spectrum lamps. Some multi-wattage digital ballasts include a dedicated 250W setting.
Can I use the same lamp from vegetative growth through flowering?
Yes. Full-cycle use is one of the main reasons for choosing a dual spectrum lamp, as it removes the need to change between separate vegetative and flowering lamps.
Why choose 250W instead of a 600W HPS lamp?
A 250W system is better suited to smaller lighting areas or installations where the additional light output, electrical demand and heat generated by a 600W system are unnecessary.
Can the lamp be used without a reflector?
A compatible reflector is normally recommended because it redirects otherwise wasted light towards the crop and helps create a more useful lighting footprint.
Does a 250W HPS lamp produce much heat?
Yes. It produces less total heat than higher-powered HID lamps, but the lamp itself still operates at a very high temperature. Suitable ventilation, clearance and safe handling remain essential.
How do I know when an HPS lamp needs replacing?
HID lamps gradually lose useful light output as they accumulate operating hours. Replacement is best based on operating time, visible lamp condition and measured lighting performance rather than waiting for complete lamp failure.
Can a 250W lamp be run at a higher ballast setting?
Only operate the lamp at settings specifically approved for the lamp and ballast combination. Do not run a 250W lamp at a higher output simply because a multi-wattage ballast offers higher settings.
How should a used HPS lamp be disposed of?
HID lamps should be sent through an appropriate lamp recycling or WEEE waste route rather than being disposed of with general waste.
