Understand Specifications
Review lumens, watts, color temperature, controls, and product ratings.
Identify Lamp Bases
Recognize connections and record the full base and fixture details.
Compare Technologies
Learn the differences among LED, halogen, fluorescent, and HID systems.
Plan Light Coverage
Review beam patterns, fixture optics, aiming, and photometric information.
Choose a Lighting Guide
Use the guide that answers your immediate question, then follow the related resources as you narrow down your replacement options.
Lighting Terminology
Understand light output, electrical input, color, installation types, fixture ratings, and service-life terms. Learn how lumens, watts, color temperature, color rendering, and other specifications describe different aspects of a lighting product.
Lamp Base Types
Identify common screw, pin-base, PAR, and tube connections. Review the markings and equipment details to record before selecting a replacement. A matching connection is only one part of confirming that a lamp is appropriate for the fixture.
Lighting Technologies
Compare LED, incandescent, halogen, fluorescent, and HID lighting systems. Understand the main retrofit approaches and the equipment information needed when evaluating a lamp replacement, fixture conversion, or complete fixture replacement.
Lighting Distribution
Learn how beam and field angles, mounting position, fixture optics, and photometric data affect coverage. Use this guide to understand why products with similar lumen ratings can produce different results in the same space.
Work Through a Specific Retrofit Question
Can the Existing Ballast Remain?
Review the LED retrofit approaches and the installation-type definitions, then check the exact lamp and ballast combination. The operating arrangement must match the requirements of the selected replacement.
Is the Fixture Enclosed?
Use the enclosed-fixture compatibility checklist to review the lamp's approval and the housing's installation conditions. Check the applicable product documents rather than assuming that physical fit establishes suitability.
Are You Replacing Halogen PAR Lamps?
The commercial halogen PAR replacement guide brings together connection, fixture fit, beam selection, and dimming considerations. Use it alongside the documents for the exact Lotus model and configuration being considered.
Move From Identification to Product Selection
Once you know the existing lamp and fixture, compare the relevant HyLite product family.
Before selecting a replacement: confirm the exact model's physical fit, electrical requirements, controls, and permitted installation conditions.
Match the Documents to the Model
The HyLite specification library provides product and installation documents. Match the full model number and configuration to the applicable file.
A familiar family name does not establish that an older document covers a newer lamp. Keep the selected product's specification sheet, installation instructions, and applicable compatibility information together.

For an example of product selection in an existing space, read the St. Bernard Catholic Church retrofit case study.
Get Help With Your Lighting Project
Gather the existing lamp model, fixture photographs, electrical and control information, and quantities. Readable photographs of the lamp, connection, and fixture label are useful when the correct replacement is not yet clear.
Our electrical contractor guide organizes those details into a project checklist and explains what to review before pricing the installation.
Send the available details to HyLite for help reviewing product options or requesting pricing.
