Pentair IntelliBrite

Pentair has discontinued the IntelliBrite. Its product page now says so and names the IntelliBrite Architectural Series as the replacement. Nothing below stops being true of the light already in your wall — this page is for owning and repairing one, not buying one.

There are two generations, and it is worth knowing which you have before ordering anything. The original IntelliBrite, in Pentair's 2009 manual, is 600101 at 120 VAC and 600104 at 12 VAC. The 5G that followed runs 601000 to 601004 at 120 VAC and 601010 to 601013 at 12 VAC, one number per cord length, and draws 26 W. Most of what follows applies to both; where the two manuals differ, the section says so.

Either way the voltage choice is the same one. The 120 VAC fixture has its 12 VAC transformer built in. The 12 VAC fixture needs an external isolating transformer that is not included — the part people leave out of the budget.

The niche rule, before anything else

Pentair puts this in a CAUTION and it deserves to be the first thing on the page:

The IntelliBrite fixture must only be used with Pentair fixture housings. Installed into another manufacturer's niche, the installation does not carry UL approval and voids all warranties.

That matters because dropping a modern LED into whatever niche is already in the wall is the normal way people convert a pool to color lighting. It usually fits. On this fixture it is not a supported installation, and the consequence is not theoretical — it is the UL listing on an electrical device submerged in a pool people swim in.

Check what is in the wall before buying the light. If local code requires a cord seal, Pentair names two plastic niches for that — 79206600 and 79206700 — and the 5G manual adds the cord seal kit, 670044, to go with them.

Fourteen positions on a wall switch

There is no remote and no app on the light itself. Everything is selected by counting how many times you flick the wall switch off and on.

Seven light shows:

• 1 — SAm, cycling white, magenta, blue and green
• 2 — Party, rapid changes
• 3 — Romance, slow transitions
• 4 — Caribbean, blues and greens
• 5 — American, red, white and blue
• 6 — California Sunset, orange, red and magenta
• 7 — Royal, deeper tones

Then five fixed colors: 8 blue, 9 green, 10 red, 11 white, 12 magenta. And two functions: 13 Hold, which saves the current point in a show, and 14 Recall, which returns to it.

So California Sunset is six cycles. Nothing illuminates during the switching, then a brief white flash, then the mode you asked for.

Why a brownout changes the color

This is the most common IntelliBrite complaint and it is not a fault.

The light counts power interruptions as switch cycles. It cannot tell your finger from a flickering utility supply, so a brownout, a storm, or a breaker tripping and resetting all count — and a light that was on white can come back on Party Mode having been asked, as far as it knows, for eleven cycles.

The rule underneath it: if power is off for more than five seconds, the light returns to the last saved mode. Shorter than that and it treats the interruption as part of a selection sequence. That five-second threshold is the whole explanation for lights that seem to change color at random, and for multiple lights on one circuit drifting out of sync with each other.

The pool light troubleshooting guide works through the rest of what looks like a broken fixture and is not.

Three hundred watts, and the arithmetic behind it

The two manuals frame the limit differently, so check which light you have.

On the 5G, the rule is written against a 300 W transformer for 12 VAC lights: no more than three pool lights and one spa light on it, and no more than 100 ft of total cable between the transformer and the lights. For long runs Pentair says to set the transformer to its 14 VAC tap.

On the original generation, the IntelliBrite Controller, 600054, caps the total at 300 watts across everything connected to it. Individually:

• Pool light — 70 W maximum
• Spa light — 40 W maximum
• Landscape light — 15 W maximum

Pentair's own example combination is two pool lights, one spa light and eight landscape lights. That is 140 plus 40 plus 120 — exactly 300. There is no headroom in the example, which is a fair signal about how seriously to take the limit.

Overloading it does not blow anything obviously. It produces dim output, flicker, and lights that will not hold sync — symptoms that look like failing fixtures. Somebody adding a second pool light or a run of landscape lights to an existing controller is the usual cause.

Ten seconds dry, and that is the whole allowance

Never run the light for more than ten seconds unless it is completely submerged. That is the original manual's figure. The 5G manual does not give an allowance at all — it simply says to fill the pool until the light is fully under water before operating it — so on a 5G treat ten seconds as the most generous reading, not a guarantee. Without water around it the assembly gets extremely hot, and the damage is not covered by anything.

That is worth planning around on a repair. Test it after the pool is full, not while it is sitting on the coping — and if the pool is being refilled, wait rather than checking the light works while the water is still coming up.

The rest of the siting rules

These are set by code as much as by Pentair, and they are worth knowing because a light in the wrong place is expensive to move:

• Lens at least 18 inches below the surface — and in Canada, not more than 20 inches deep
• Junction box or low-voltage transformer at least 8 inches above the maximum water level, and at least 48 inches from the pool edge
• GFCI on the lighting circuit for line-voltage models
• The niche bonded and grounded via the No. 8 AWG connector at the rear, and everything metal within five feet of the pool bonded

And one absolute: never splice wire underwater or behind the niche to replace a light. Pentair says "under no circumstances", and it is the one instruction here where the consequence is not an equipment failure.

The one consumable

There is exactly one part you must buy every time this fixture comes apart: the lens gasket, and the number depends on the generation. The 5G takes 620400Z; the original takes 79101600. Pentair's 5G manual gives 620400Z in its English and Spanish instructions and its parts table, but its French section still prints 79101600, the original's number. Go by the parts table.

Pentair puts it in capitals — a new lens gasket must be used each time the light is reassembled. Not inspected, not reused because it looks fine. It costs very little and it is the only thing keeping water out of an electrical fixture that lives underwater.

If the pool is salt, expect the stainless face ring to be the part that shows age first. Pentair carries a specific warning that salt increases corrosion of metal parts in and around a pool, and the face ring is the most visible piece of metal in the wall.
