Which Limelight Spa Do You Own? A Model Identification Guide for Ordering the Right Parts

Ordering a replacement part for your hot tub is simple, until you realize you are not completely sure which model you have. Limelight spas share a family design, and several models look similar from the outside, but filters, heaters, covers, pillows, and electrical requirements can all differ by model and model year. Ordering the wrong part costs time, return shipping, and days without your spa.

This guide shows you how to confirm exactly which Limelight model you own, summarizes the specifications of the Limelight Collection lineup, and explains which details matter most for the parts you are most likely to order.

Step One: Find Your Serial Number Label

The most reliable way to identify your spa is the serial number and identification label, which Hot Spring places inside the equipment compartment. The label lists the model, and the serial number encodes production details that help confirm the correct parts for your spa's year. Before you order anything, write down:

• The model name or model code
• The full serial number
• The electrical rating shown on the label
• The approximate year you bought the spa

Always turn off power to the spa at the breaker before removing the equipment compartment door. Keep a photo of the label on your phone so you have it handy whenever you shop for parts. If the label is hard to read because of glare or fading, try photographing it with your phone's flash off and a flashlight held at an angle, which often makes faded print easier to read. The same serial number is also needed to register the spa and use its warranty coverage, so it is worth recording even if you do not need parts today.

The Limelight Collection Lineup

The specifications below come from Hot Spring's 2019 Limelight Collection owner's manual. Limelight model names and specifications have changed over the years, so if your spa is older or newer, use the serial label and your own owner's manual as the final word.

Telling Look-Alike Models Apart

Flair and Flash share the same 7 foot by 7 foot footprint and 36 inch depth, which makes them easy to confuse by measurement alone. The difference is in the seating layout and capacity: Flair seats 6 and holds about 335 gallons, while Flash seats 7 and holds about 360 gallons. The serial label settles it.

The two Beam versions look identical but have different electrical setups. The BMI is a 115 volt model, while the BMII is a 230 volt model. That difference affects heater parts and electrical components, so it matters when ordering.

If your label is missing or unreadable, measure the spa's length, width, and height, count the seats, and note the lounge position. Then contact our team with those details and photos of the interior layout.

Which Details Matter for Which Parts

Covers

Covers depend on exact dimensions and corner radius, not just the model name. Even within one model, dimensions can vary by year. Confirm model and year, and measure your current cover before ordering a replacement.

Filters

Filter area differs across the lineup: 150 square feet on the Prism and 100 square feet on the Pulse, Flair, Flash, and Beam in the 2019 lineup. Filter style and fittings can also change between model years, so match the filter to your model and year.

Heaters and Electrical Parts

Heater wattage varies from 4,000 watts on most 230 volt models to 6,000 watts on the Beam, and the 115 volt Beam has its own configuration. Always match heater, control box, and electrical parts to the exact model and electrical rating on your label.

Pillows, Jets, and Trim

These often change with shell design updates, so model year is just as important as model name. Photos of your existing part alongside your serial number make matching much easier.

Other Clues That Help Identify Older Spas

If your spa predates the models listed above, or its label has faded, a few other details can help narrow things down. The style of the control panel is one of the best clues, since Hot Spring has updated its panels over the years, and panel style often lines up with a specific range of model years. The water care system is another. Spas with the ACE salt system generally come from an earlier generation than spas equipped for the FreshWater Salt System. Photos of the jets, pillows, filter lid, and cabinet corners also help, because these details changed as the shells were redesigned.

Your purchase paperwork, warranty registration, and original owner's manual are also worth digging out. Any of them may list the model and serial number, and the manual's specification page confirms dimensions, gallons, and electrical requirements for your exact year.

Building a Simple Spa Record

Once you have confirmed your model, create a simple record you can refer to for years. Include the model and serial number, electrical rating, filter part number, cover dimensions, the date of your last filter change, and the date you last replaced major parts. Store it in a note on your phone or in a folder with your owner's manual. The next time you need a filter, a pillow, or a replacement cover, you will have everything needed to order in minutes, and a technician will have the details they need if your spa ever requires service. If you sell your home or your spa, that record is also a helpful document to pass along to the next owner.

Why Filled Weight Matters for Placement

The filled weights above include water but typically not bathers. They are a reminder of why a Limelight spa needs a solid, level foundation, and why decks or elevated surfaces should be evaluated by a qualified professional before installation. If you are relocating or reinstalling a spa, the model's filled weight is one of the first numbers to share with your contractor.

Frequently Asked Questions

Where is the model information on my Limelight spa?

Look for the serial number and identification label inside the equipment compartment. Turn off power at the breaker before removing the compartment door.

How can I tell a Limelight Flair from a Flash?

Both measure 7 feet by 7 feet and 36 inches deep in the 2019 lineup. The Flair seats 6 and holds about 335 gallons, and the Flash seats 7 and holds about 360 gallons. The serial label is the most reliable way to confirm.

Is the Limelight Beam a plug-in spa?

The Beam comes in two versions. The BMI runs on 115 volt power on a 20 amp dedicated circuit, and the BMII runs on 230 volt, 50 amp power.

Do all Limelight spas use the same filter?

No. In the 2019 lineup, the Prism uses 150 square feet of filter area and the other models use 100 square feet. Match the filter to your model and year.

What should I have ready when ordering parts?

Your model, full serial number, electrical rating, approximate purchase year, and a photo of the part you are replacing.

A few minutes spent confirming your Limelight model saves days of frustration later. Photograph your serial label, keep your model's key specs handy, and match every part to both model and year. Whether you need a filter, a cover, or a heater component, you will order the right part the first time.
