200+ decorative lights converted with the Post Top Pearl.
Replaced failing corn-cob lamps and sockets · earned rebates

Field conversion kit that turns a classic post top into a like-new LED fixture, keeping the existing housing and globe, for under 20% of the cost of new.
The Post Top Pearl lets cities, campuses and property owners keep the charm of their existing decorative post tops while eliminating lamp and ballast maintenance. Originally engineered as an OEM post-top engine, it is now offered with the same performance as a field conversion.

Post Top Pearl® Light System
Preserve historical and architectural post-top luminaires while using current LED and control technology. The fixture stays on the pole. The globe stays. Only the light system changes.
“We had too many experiences with light engines that are un-serviceable or would tilt in the fixture because of a bad mount. We wanted a quality product that would withstand the tough conditions of a street light.”
Municipal lighting program manager
All units assembled and tested in Georgia. Heavy-duty, all-metal construction. Lead times around two weeks, no minimum order.
Pre-designed LED conversion kits for the most common decorative fixtures. Each kit is engineered to its fixture: exact fit, light distribution matched to the original, installed in the field with OEM performance.

Utilities and cities call us when the OEM answer is too expensive or too hard to install. A few Holophane examples:
Problem: The globe weighs over 40 lb and is very difficult to remove.
HiLumz: Designed a kit that installs without removing the globe.
Problem: The utility rejected the OEM retrofit kit as too difficult to install.
HiLumz: Built a custom 10-minute install kit at half the competitor's price.
Problem: The utility spent 3+ years trying to sell new fixtures but couldn't meet the city's budget.
HiLumz: A retrofit solution 80% less expensive than the competitor.
Why a proper light system beats a screw-in corn cob lamp. Your fixture deserves an OEM-quality light system.
| Post Top Pearl® | Corn cob lamp | |
|---|---|---|
| Aesthetics | Solid fit, proper light throw, optional diffused lens. OEM look with street-side or house-side optics. | No height adjustment, cheap look in daytime, glare at night. |
| Strength | Direct mount for a permanently tight fit. No tilt in a vibrating fixture. | Socket was never designed for a heavy lamp and driver. Often leads to wobble. |
| Electricals | Class II low-voltage DC into the globe. No heat at the socket. | Line voltage through the socket. Heat erodes the porcelain. |
| Product life | External driver and surge protection keep heat away from the light engine. | Driver packed into the lamp, compounding heat and cutting life. |
| Controls | DALI-2, Bluetooth mesh, photocell in the base or on top, 0-10V dimming. | Some have a tiny built-in photocell — more electronics in the same hot space. |
| Service | Replace the driver or the light engine on its own. | Replace the whole lamp, then try to match the light. |
| Installation | Quick kit install. Screw-in option available. | Ballast must be bypassed, or kept as one more failure point. |
| 70 W example | 252 LEDs · no fan needed · steel and aluminum construction · aluminum driver casing | 96 LEDs · fan required · plastic construction and driver casing |
| Rated life | 100,000 hours (10+ years) | 70,000 hours |
| Wiring & mount | Direct-wired, steel bolts into aluminum | Old socket, plastic base |
| Assembled in | Georgia, USA | China |
| Proof | Decorative post top OEMs use integrated light systems. | Quality OEMs don't use corn cobs. |
Every Pearl® system is built around your fixture, your spec and your install conditions. Standard options are below — custom builds are routine.




Built to utility requirements. Ask about project-specific specs.
The finished fixture looks like it was designed for LED. Multiple installation options, colors, lumen packages and optics deliver clean down light to the street or walkway, replacing metal halide, high pressure sodium, amber, or failing corn-cob lamps.
