Hayward AstroLite 500W Incandescent Pool Light: 100-Foot Cord with Stainless Steel Trim for Extended Conduit Runs
The 100-foot cord on this AstroLite is the right specification when the conduit route from the light niche to the junction box exceeds 50 feet along the actual routed path, not a straight-line estimate across the pool. The stainless steel trim is required when the existing niche uses a metal trim ring connected to the equipotential bonding grid, or when the pool design specifies metal hardware throughout. Any cord beyond the conduit run coils inside the niche behind the fixture, stored permanently and available to pull the fixture out to the pool deck during future service without disconnecting at the junction box.
Stainless Steel Trim vs. Thermoplastic Trim: Choosing the Right Trim for Your Niche
Stainless trim is the correct choice when the existing niche uses a metal trim ring connected to the bonding grid, when the design specifies metal for aesthetic continuity with other pool hardware, or in saltwater or coastal environments where material consistency matters. Thermoplastic trim is non-conductive and appropriate when the niche does not route bonding through the trim ring, and costs less. If uncertain about which applies to your niche, the installing licensed electrician's assessment is the authoritative guide before ordering.

Hayward AstroLite 500W Stainless Steel Trim 100-Foot Cord Frequently Asked Questions
Why would I need the 100-foot cord over the 50-foot version?
Only one reason: the conduit run from the niche to the junction box exceeds 50 feet along the actual routed path. The fixture, trim ring, bulb output, and bonding compatibility are identical across cord lengths. Have the installing electrician pull a tape through the existing conduit before ordering. When the run is close to 50 feet, the 100-foot version eliminates the risk of arriving on installation day with a cord that cannot reach the junction box, since the cord cannot be extended after installation.
Does the stainless trim ring include a bonding lug?
Confirm with the installation guide and the installing electrician. Some stainless trim rings include a pre-drilled hole or lug for attaching the bonding conductor; others rely on the electrician to attach the bonding connection using an approved clamp or method. The specific bonding connection approach must comply with the local code interpretation of NEC Article 680 requirements for underwater pool lighting.
Which niches is this fixture compatible with?
The AstroLite mounts in specific Hayward DuraNiche housings: SP0600U/SP0600 for concrete pools, SP0607U/SP0607 for vinyl and fiberglass pools, and SP0604C/SP0609C stainless steel niches for concrete. Note that SP0600 and SP0607 niches are no longer manufactured; confirm your existing niche model before ordering if it is an older installation.
Is the niche included?
No. The AstroLite is sold without the niche. If reusing an existing niche, confirm its model and that the trim ring dimensions are compatible with this fixture before ordering.
Should I upgrade to an LED instead of replacing with another AstroLite?
If the pool light runs several nights per week, the 500W operating cost becomes a meaningful annual electricity expense compared to a comparable LED fixture. An LED replacement at 120V in the same niche type also eliminates recurring bulb replacement for its rated service life and adds color-changing capability. The AstroLite remains the right choice when upfront cost, incandescent light quality preference, or niche compatibility uncertainty favor a direct like-for-like replacement.
