GW CS8PM1.EM-LRLT-XX57 ams OSRAM OSLON SSL 80 3000K Warm White Emitter

Product Introduction

The two letters in the middle of the part number are not arbitrary. LRLT names the first and last rungs of the brightness ladder the code covers - LR opens at 130 lm, LT closes at 164 lm, and LS sits between them. Every code in this family spans exactly three consecutive groups.

Those windows slide upward as the colour temperature cools. The 2500 K code covers LP to LR, 2700 K covers LQ to LS, 3000 K and 3500 K both cover LR to LT, and 4000 K upward cover LS to LU. The family's output floor therefore climbs from 112 lm at the warm end to 140 lm at the cool end, and the span widens from 28 lm to 40 lm as it goes.

GW CS8PM1.EM-LRLT-XX57 sits on the LR-to-LT window at 3000 K, ordering number Q65113A5706, in full production. It is the warmest colour temperature here that reaches a 130 lm floor: one step warmer starts 9 lm lower and stops 14 lm shorter. The commercial string adds -1, -350 and -R18 for the version, the 350 mA test point and the reel.

Key Product Features

1. A Code That Names Its Own Brightness Window
The four letters are not a serial; they are the endpoints of the group range. Reading LRLT as LR-through-LT tells a buyer what the reel can contain without opening the datasheet.

2. Three Groups Per Code, and a Span That Widens With Colour
The window is always three rungs, but the rungs themselves grow as output rises, so the supplied range runs 28 lm wide at 2500 K and 40 lm wide from 4000 K up. A warm-white buyer gets a tighter spread than a cool-white one.

3. The Warmest Colour Temperature to Reach 130 lm
Step one warmer and the window drops to LQ to LS, opening 9 lm lower and closing 14 lm shorter. Step cooler and nothing changes until 4000 K. For a 3000 K specification there is no output penalty to weigh against the colour.

4. The Ladder Stops at 5000 K
The family carries seven codes from 2500 K to 5000 K and no further. A requirement above that leaves this datasheet for the CRI 70 sibling, which shares the footprint and the beam but not the colour rendering.

5. One Code Per Colour Temperature
All seven rows are XX-codes, so there is no parallel A-code to cross-check a second reference against. The table is the whole list, which makes the sourcing question simpler than in families that carry two nomenclatures.

Application Fields

Warm white at 3000 K is chosen by the end client as often as by the engineer, so these are fixtures where the colour has to sit beside warm sources already in the room. Typical specifications include:

- Restaurant and bar table lighting – low-glare spots over a table, seen from a seated height.
- Residential downlighting – the domestic warm point that interior schemes are drawn around.
- Hotel corridors and lobbies – long runs of matching fixtures where consistency beats peak output.
- Retail fitting rooms – warm light across skin and fabric, where rendering is noticed at once.
- Boutique window and shelf spots – close-range accents sitting under a warm ambient level.
- Period and heritage interiors – replacements that have to read alongside older warm sources.
- Warm-white track and rail heads – adjustable fixtures in a space already lit at 3000 K.
- Entertainment and stage rigs – one of the three applications the manufacturer names for this family.
- Indoor general lighting engines – the manufacturer's second listing, where a narrow cone is usually shaped further by a diffuser.
- Outdoor and industrial housings – the manufacturer's third listing; the ceramic body keeps its geometry across thermal cycling.

Why Choose Gainer LED?

- Reel-level traceability on every consignment
We record the group name from each reel against the shipment, so a build can be traced back to the bin it was assembled from long after the boxes are gone.

- Order quantities quoted at the reel and the carton
Both breaks are on the quotation, so a buyer can see what the next quantity step costs before committing rather than after.

- Colour consistency held across repeat orders
Where a project ships in phases we aim to keep successive batches in the same chromaticity group, and we say so in advance when a batch cannot be matched.

- Agreements confirmed in writing
Anything settled on a call is put in writing the same day, so the order file holds the version both sides are working from.

- Export documentation prepared in-house
Origin papers, packing list and the destination paperwork are raised by us rather than left to a forwarder to interpret.
