ams OSRAM DURIS E 2835 GW JTLMS3.CM-G8GW-XX56-1-60 3500K Warm White CRI 90 SOFTLINEAR LED

Product Introduction

Picking 3500 K is usually about materials, not light output. The GW JTLMS3.CM-G8GW-XX56-1-60 is the warm white option in the ams OSRAM DURIS E 2835 family, the 0.2 W SOFTLINEAR build for flexible strips, and its colour point sits at Cx 0.4077 and Cy 0.3929. That is the warmer side of neutral: near enough to 3000 K for timber and textile tones, far enough away to avoid a yellow cast.

Colour quality is what separates it from a general-purpose 2835. CRI holds at 90 minimum and 92 typical, and R9 does not drop below 50, so saturated reds and skin tones survive rather than flattening. Light leaves the moulded resin at 120° Lambertian, which suits long runs.

Flux spans 22.5 to 28.5 lm at the 60 mA test point. Two voltage groups cover the whole family, both inside a 2.80 to 3.00 V band, so a 2.90 V typical part keeps a strip current-shared without special selection. Thermal resistance measures 42 K/W against a 105 °C junction ceiling.

Key Product Features

1. 3500 K Held Inside a Five-Step Ellipse：The datasheet defines this colour as a coordinate pair and an ellipse, not a colour name. With semi-axes of 0.0155 and 0.0069, the window is a quadrangle that a brand colour standard can be checked against before an order is placed.
2. CRI 90 and R9 50, with the R9 Tolerance Defined at 4000 K：The glossary states the ±6 R9 tolerance at 4000 K. That is worth knowing on a 3500 K code, because it means R9 should be treated as a minimum rather than a figure held to the same band as the rest of the CRI specification.
3. No Surge Rating, So the Continuous Limit Governs：Unlike many mid-power emitters, this family publishes no surge current figure and no pulse handling curve. PWM dimming and inrush design therefore have to sit inside the 90 mA continuous maximum and the derating curve.
4. IEC 62471 Low-Risk Classification：The part falls into the low-risk group at a 100 s exposure time. That is a step above exempt, and it belongs in the luminaire's own photobiological assessment rather than being assumed away.
5. Neighbouring Colour Points on One Footprint：The 3000 K code Q65113A6710 and the 4000 K code Q65113A6700 share this board layout and this reel format. A project that later needs to move warmer or cooler changes a line on the order, not the board.

Application Fields

This 3500 K emitter suits interiors where 4000 K would read too clinical and 3000 K would read too amber. Typical specifications include:

- Residential and hospitality strips – warm ambient tape light for hotel rooms, restaurants, and living spaces.
- Warm cove and niche lighting – concealed runs where 3500 K flatters timber, stone, and plaster.
- Hotel corridors and lobby linear runs – continuous lines where the warmer point keeps a large space relaxed rather than clinical.
- Restaurant and bar accent strips – back-bar and banquette lighting where CRI 90 keeps food and drink looking right.
- Retail fitting in warm-toned interiors – apparel and furnishing displays where a cooler white would drain the material colour.
- Furniture-integrated lighting – shelf and wardrobe strips built into joinery, matching what residential buyers expect.
- Textile and wood showrooms – displays where a warm point stops natural materials turning grey.
- Residential panel and troffer retrofits – 600 × 600 mm and 300 × 1200 mm panels specified between 3000 K and 4000 K.
- Warm linear luminaires and battens – continuous rows in interiors that sit between the two common colour temperatures.
- Signage and light boxes in warm interiors – backlighting that has to agree with the lighting around it.

Why Choose Gainer LED?

- We quote the colour point, not just the colour temperature："3500 K" is a label. The datasheet defines it as Cx 0.4077 and Cy 0.3929 inside a five-step ellipse, and we put those coordinates on the quotation so a brand standard can be checked before the order rather than after delivery.
- The R9 tolerance is explained before you lean on it：The ±6 R9 tolerance in the datasheet glossary is stated at 4000 K. We flag that on this 3500 K code instead of letting a colour-critical project assume the same hold applies at every colour temperature in the family.
- Where no surge rating exists, we say so：This family publishes no surge current figure and no pulse handling curve. A PWM design has to live inside the 90 mA continuous limit, and we raise that at quotation rather than leaving a designer to find out at the prototype stage.
- Colour-temperature advice before the order, not after：If a drawing specifies 3500 K but the surrounding lighting runs at 4000 K, the mismatch will show in the finished space and land on the supplier. We say so while the specification can still change.
- We work the thermal arithmetic with you：Drive current, emitters per metre, and the 42 K/W path against the 105 °C junction limit. We run that calculation on your strip design and put the answer in writing, so the derating decision is documented rather than assumed.
- Two MacAdam grades of the same 3500 K, quoted together：This ordering code is the five-step version. ams OSRAM also lists a three-step 3500 K as Q65113A8847, and we price both so the cost of the tighter window is visible before a reel is committed.
