Best Double-Ended Grow Lights Reviews (2024)

1. TopoGrow 1000W Double Ended HPS Grow Light

  • Watts operation:- 1000 watts
  • Type:- HPS Double-Ended Grow Light Kit
  • Warranty:- Manufacturer’s Warranty

Double-ended grow lights with hps bulbs aren’t always the most efficient, don’t always distribute light too well, and can have shorter-than-expected lifespans. So, when you’re entering the world of cannabis-growing equipment in search of lights like these, it doesn’t hurt to have some guidance like ours to find what you’re looking for. We couldn’t help ourselves — we had to kick our list off with a double-ended light + HPS bulb combo review because the TopoGrow 1000W Double-Ended HPS Grow Light is just that good.

The TopoGrow 1000W is one of the best double-ended lights with a dimmable ballast for a few reasons: it’s got one of the highest efficiency levels on the market, has a ridiculously long operating life, and distributes light incredibly effectively. Its double-ended system delivers a huge PAR value with incredible uniformity, and its unique open design guarantees maximum light output and optimal levels of heat management.

One of the first things we noticed when we gave this product a spin was its DE-enclosed reflector. The TopoGrow 1000W DE HPS Grow Light is probably one of the best double-ended lights with an enclosed reflector that we’ve ever seen; the reflector is made of imported German aluminum and boasts an impressive premium aluminum European hammer-tone interior. We found this light to be highly efficient for overlapping footprints of multi-light configurations, and it seemed to provide a much higher percentage of available energy than other HPS lamps.

With this double-ended HPS grow light kit fixture, yields are guaranteed to be impressive (definitely more impressive than yields you’ve gotten from any other DE + HPS combo you’ve used in the past). The model comes in different variants, and you can opt for either open or enclosed hoods. If you’re in the market for a light that’ll help with a massive grow area that has multiple plants, you can’t go wrong with the TopoGrow 1000 Double-Ended HPS Grow Light.

Pros
  • Extremely powerful
  • Dimmable ballast with operational watts settings

A couple of our favorite things about the Nanolux DE Fixture were its plug-and-play installation capabilities and the fact that its ceramic lamp receptacles weren’t at all susceptible to melting. Its design is perfect for a 5′ x 5′ growing grid. The best part, though, was that the Nanolux DE 1000W is great for footprints that overlap in grow areas with multi-light configurations.

There is also the added benefit of the compatibility of this fixture’s light with the Nanolux cloud control system, which works with the Nanolux mobile app. The Nanolux DE 1000 DE Fixture is among the most trusted options worldwide and is backed by a manufacturer’s warranty.

Buyer’s Guide to Double-Ended (DE) Grow Lights.

Don’t know much about DE grow lights? We’ve whipped up a handy little guide for you.

These types of lights fall under the category of grow lights, which also has a separate sub-category for single-ended grow lights. These lights are different due to their HID bulbs, which are comprised of either HPS or Metal Halide and fit into a reflector.

The distinguishing feature of the double-ended grow light is that it has a robust operation with connections at both ends, which offers bright operation against its single-ended counterparts. The single-ended grow lights are the same as double-ended but are only connected with power at one end.

The distinguishing feature of a double-ended grow light is its robust operation that includes connections at either end, allowing for a brighter operation when compared to single-ended lights. One thing to note about DE lights is that, because of how powerfully they operate, they can experience issues with heating. This intense heat is due to the double-ended connection. With that said, many users prefer DE grow lights over single-ended lights or LED lights if they’re working with large grow areas with multi-light configurations.

Frequently Asked Questions (FAQs) Regarding DE Grow Lights

1. Are double-ended grow lights better?

Double-ended grow lights have been largely replaced by LED grow lights. However, they have been used for growing plants and marijuana for a long time and are still good choices for large grow operations.

2. What are double-ended grow lights?

Double-ended grow lights are HPS- and MH bulb-equipped grow lights, which have electric fixture connections on both ends. The double-ended connection offers power, brightness, and efficiency, making DE grow lights ideal for growing cannabis plants.

3. How long do double-ended bulbs last?

Double-ended bulbs last a very long time. They need no early replacement and last up to 10,000 hours.

4. Is it okay to put a 600w bulb in a 1000w ballast?

Using a 600w bulb in a non-dimmable ballast of 1000W is not ideal. However, with a dimmable ballast, it is possible and ideal to use a 600W bulb with a capacity of 1000W by dimming the setting to 600W of light output.

5. Are HPS or LED grow lights better?

LED grow lights are better than HPS lights as they are more advanced, modern, and energy-efficient. LED grow lights use less power, are comparatively cooler, have a full spectrum of light output, and can be customized to suit various stages of plant growth. However, HPS grow lights are functional and are still in use in the context of indoor horticulture.

6. Are double-ended grow lights still worthwhile compared to LED grow lights?

LED grow lights are typically the better choice, but DE grow lights are still ideal to use if you prefer them for large grow operations with multi-light configurations.

7. What’s the difference between Double-Ended (DE) and Single-Ended Grow Lights?

A double-ended grow light, as the name suggests, is connected to electric fixtures from both ends. A single-ended grow light, again as the name suggests, is single-ended, and is connected to an electric fixture from just one end. DE grow lights also draw more power and provide a higher energy output compared to single-ended grow lights.

8. What’s the best type of DE grow light to purchase?

DE grow lights are available with a variety of bulbs. The different types of bulbs are HPS (High-Pressure Sodium), CMH (Ceramic Metal Halide), and Metal Halide. The best amongst them or widely preferred is the HPS bulb, which is bright and draws a large amount of energy.
