Astralpool Halo Lite 2
Astralpool Halo Lite 2 is backordered and will ship as soon as it is back in stock.
AstralPool Halo Lite 2 & Halo Lite 4 are next-generation pool light controllers with built-in transformers. Control compatible pool lights from your phone via Bluetooth, choose colours or sequences, and set schedules using the free app.
This item available for pick-up only at 10 Industry Blvd, Carrum Downs VIC
Quick highlights
- Built-in transformers (no separate transformer box required)
- Bluetooth phone control using the Halo Lite app
- Schedules & automation from your smart device
- Two models: Halo Lite 2 (2 lights, single zone) or Halo Lite 4 (4 lights, multi-zone capable)
- Integrates with Halo Connect (for expanded zoning and control)
Why Halo Lite is different
Most pool light controllers rely on additional transformers and small remotes that are easy to misplace. Halo Lite has the transformer built into the controller and uses Bluetooth control through your phone, so you always have control when you need it.
Using the app, you can:
- Select a colour or sequence at any time
- Set schedules for lights to turn on and off automatically
- Manage multiple Halo Lite controllers from the one app
DIY retrofit and upgrade
Halo Lite is designed to be an easy upgrade for many existing pool lighting setups.
- Single colour lights: can be retrofitted to most brands (check power specifications)
- Multi colour lights: compatible with AstralPool, Zodiac, and Spa Electrics multi-colour pool lights (check power specifications)
Connect your existing low-voltage pool lights to Halo Lite and you are ready to go. No tiny remotes to lose, and control is right from your phone.
Choose your model
- Halo Lite 2: two-light control transformer, controls 2 multi-colour lights across a single zone
- Halo Lite 4: four-light control transformer, controls 4 multi-colour lights and supports multi-zone setups when integrated with Halo Connect
Expansion and zones (Halo Lite 4)
- If using the Halo Lite app as a standalone controller, 1 zone is available.
- If used with Connect 10, you can assign all 4 lights to Zone 1 or Zone 2.
- You can link up to 5 x Halo Lite 4 together via RJ12 cable to control up to 20 lights in 1 zone (via the app or an external low-voltage switch).
- Note: If using a Halo chlorinator, up to 4 zones are available.
Whole backyard control
Halo Lite can be used beyond pool lighting. Through the Halo Lite app you can connect multiple Halo Lite controllers and automate lighting across your backyard, including pool lights, garden lights, and water feature lights (check power specifications).
Important notes
- Always confirm your light type and power specifications before purchase or installation.
- Bluetooth control range depends on device location and site conditions.
- *Zoning features vary depending on whether Halo Lite is used standalone or integrated with Halo Connect.
In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1/2" | 15mm | ~21.2–21.5 mm |
| 3/4" | 20mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions1.
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
| 4" BSP | 113.03 mm / 4.450" | 11 |
| 5" BSP | 138.43 mm / 5.450" | 11 |
| 6" BSP | 163.83 mm / 6.450" | 11 |
