Detail 01
Blacklight (BLB) lamp
Emits UV rather than visible light, so it makes white and fluorescent materials glow instead of lighting the room.

Lamp LiteLL-400BLB Replacement Lamp
Independent shopping perspective
The Korena take
A replacement blacklight lamp for Lamp Lite LL-400BLB fixtures. Buy it when your existing UV lamp has burned out or dimmed.
Strong match
Who this is for
- Restoring output on a UV fixture that has gone dim
- Keeping a spare on hand for mobile lighting rigs
- Replacing a failed lamp mid-season without swapping the fixture
Consider the trade-offs
When to look elsewhere
- Anyone needing white or colored output — this is a blacklight lamp
- Fixtures that take a different lamp type or base
- LED fixtures, which have no user-replaceable lamp
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
LL-400BLB replacement
Model-specific part. The base and envelope are matched to the fixture, so it seats without adapters.
Detail 03
Consumable lamp, not a fixture
You are buying the bulb only. It goes into a housing you already own.
Final check
Know before you order
- 01Check your fixture's lamp code before ordering — codes differ by a letter or two
- 02Let the fixture cool fully before opening it to swap the lamp
- 03Handle the glass with a cloth; skin oils create hot spots that shorten lamp life
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come with the fixture?
No. This is the replacement lamp only. It installs into a Lamp Lite housing you already own.
02Why is my UV output weaker than when it was new?
UV lamps lose output well before they fail outright. A lamp that still lights but no longer makes whites glow strongly is due for replacement.
03Can I touch the glass when installing it?
Use a cloth or gloves. Oil from your fingers bakes onto the glass and creates a hot spot that can shorten lamp life.
04How do I know I need this exact lamp?
Match the code printed on your old lamp or in the fixture's manual to LL-400BLB. Similar-looking lamps with different codes are not interchangeable.
