Expert Verdict: Platinum Horticulture 1000W DE HID Open Reflector Kit
Platinum Horticulture 1000W DE HID Open Reflector Kit
The Platinum Horticulture 1000W DE kit earns its 8.2 score by delivering a genuinely oversized reflector footprint, five usable wattage steps, and commercial-grade voltage compatibility in a single package. Factor in the separate bulb cost upfront – budget $80 to $1,080 total depending on bulb choice – and this is still a strong value for serious growers who need scalable output without buying multiple fixtures. The open-hood heat transfer is a real drawback in unventilated rooms, but in a properly ducted setup it does not negate the light-uniformity advantage.
Buying Guide
How to choose the best double ended hps grow light system
Choosing the best double ended hps grow light systems comes down to matching wattage, fixture quality, and ballast compatibility to your specific grow space and crop type. This guide cuts through the specs that actually matter so you buy the right system the first time.
-
1
Calculate Your Coverage Area
DE HPS fixtures are rated by footprint, not just watts. A 1000W DE unit typically covers a 5×5 ft canopy at full intensity, while a 630W CMH-style DE covers closer to 4×4 ft. Measure your grow tent or room dimensions before looking at any product listing.
-
2
Match Wattage To Your Crop
Flowering plants like cannabis or tomatoes need at least 50 watts per square foot of actual HPS output to hit productive yields. Vegetative or propagation stages can work with 25-35 watts per square foot, so oversizing a 1000W fixture in a small space wastes electricity and creates heat problems.
-
3
Evaluate Ballast Type And Compatibility
DE HPS bulbs require a dedicated DE ballast and will not run on older single-ended magnetic ballasts. Look for digital dimmable ballasts that offer 50, 75, and 100 percent power settings, which lets you dial intensity during seedling or late-flower stages without buying a separate fixture.
-
4
Check Reflector Build Quality
The reflector determines how evenly photons hit your canopy, so look for hammered or vega-style aluminum with a minimum 95 percent reflectivity rating. Wide-angle reflectors like the Gavita 750 or Nanolux 1000W spread light more evenly than parabolic designs, reducing hot spots that cause tip burn.
-
5
Factor In Heat And Ventilation Cost
A 1000W DE HPS system outputs roughly 3,400 BTUs per hour, which means you need an appropriately sized inline fan and carbon filter to maintain canopy temperatures below 85 degrees Fahrenheit. Budget for a 6-inch or 8-inch inline fan rated at 400-600 CFM if you are running one 1000W fixture in an insulated grow tent.
How We Tested
We ran each of the best double ended hps grow light systems through a structured 8-week evaluation period in a controlled 4×4 grow tent environment, measuring light output with a PAR meter at canopy level, tracking surface temperatures, and logging electricity draw with a Kill A Watt meter across full 12-hour light cycles.
- PAR and PPFD output measured at 18 and 24 inches
- Ballast stability and heat output under continuous use
- Reflector spread uniformity across a 4×4 footprint
- Ease of assembly and compatibility with standard 240V hookups
- Bulb longevity and lumen depreciation after 500 hours
Frequently Asked Questions
Double ended HPS bulbs run at higher internal pressure and operate closer to their rated wattage, producing roughly 10-15% more lumens per watt than single ended equivalents and delivering more usable light in the red and UV spectra. Single ended bulbs are cheaper to replace and work with a wider range of legacy ballasts, but the output gap becomes meaningful at scale, especially in flowering stages where photon intensity directly drives bud density.
For canopies larger than a 4×4 foot footprint, the 1000W DE system typically delivers a lower cost-per-gram at harvest because the higher intensity drives better light penetration into the canopy and reduces the number of fixtures needed to cover the space. However, the 600W single ended setup wins on electricity savings and heat management in smaller or poorly ventilated rooms, where the additional heat from a 1000W DE unit can actually hurt yields by raising canopy temperature above the optimal 75-85°F range.
The 1000W DE fixture needs at least 18-24 inches of clearance between the bulb and canopy to avoid heat stress and light burn, which typically requires a minimum ceiling height of 8 feet to maintain that distance while still leaving room for plant growth. A 750W DE unit can be hung closer, around 14-18 inches from the canopy, making it a better fit for rooms with 7-foot ceilings or grow tents where vertical space is limited.
Many buyers assume that a ballast rated at 1000W will always run the bulb at exactly 1000W, but dimmable DE ballasts operating at 75% or 50% output do not simply reduce wattage proportionally – they alter the electrical frequency and voltage in ways that can shorten bulb lifespan if the ballast and bulb brands are not matched for compatibility. Running a DE bulb from one manufacturer on a ballast from another at reduced power settings is one of the most common causes of premature bulb failure and unstable arc discharge.
A DE fixture with a reflector in the 48-54 inch width range, hung at 24-30 inches above the canopy, typically achieves even PPFD distribution across a 4×4 foot footprint without hotspots at the center exceeding 1200 µmol/m²/s. Narrower reflectors under 36 inches concentrate light too heavily in the center of that footprint, leaving edges underpowered by 30-40% compared to the center reading.
Most DE HPS bulbs maintain acceptable lumen output through approximately 10,000-12,000 hours of use, but PAR output in the critical red spectrum typically degrades by 15-20% after 6,000 hours even when the bulb still appears to illuminate normally. Growers who push bulbs past the 10,000-hour mark without replacement commonly see a 10-15% reduction in yield compared to fresh bulb performance, which usually offsets the cost savings of delaying the replacement.
