Product Specifications and Their Limits
The TITK LED filament bulb displays a classic ST64 shape with an E27 base. The base designation alone does not establish electrical or mechanical compatibility with a particular fixture. Its clear glass enclosure emphasizes the filament design, which enhances decorative impact particularly in retail, hospitality, or themed spaces. The bulb operates at a low power consumption of 2 watts and has recorded values of 80 lumens and red light. The product record also lists CRI 80. Request the relevant measurement report and confirm how these optical values apply to this red-light model; do not infer color accuracy or task-lighting suitability from the recorded CRI alone.
Voltage specifications include DC3V, 3.7V, and 5V options, emphasizing application in low voltage direct current systems rather than standard alternating current mains. Buyers must confirm whether their electrical environments support these DC voltages or require additional components such as drivers or transformers. The bulb measures 64 mm in diameter with a height of 140 mm, and requires fixture fit verification. The product library describes this model as dimmable, but the specific control method and compatible power supply still require confirmation. Obtain model-specific documentation for lifespan, certifications and safety approval before relying on those claims.


Applications and Electrical Questions
The recorded red light and ST64 form make this model a candidate for evaluation in accent and ambient decorative lighting in cafes, bars, boutiques, hotel zones, and artistic environments. The relatively low lumen output suits use cases focused on atmosphere rather than general brightness, reinforcing its specialty as a mood lighting element.
Due to its DC voltage design, buyers should carefully assess how the bulb fits into their power architectures. Most global installations rely on mains AC power, so compatible drivers or power supplies might be required to use this bulb safely and effectively. Key electrical questions include whether the bulb supports dimming, compatible driver types and specifications, operating voltage tolerances, and environmental operating limits such as temperature and humidity ranges. Reliability considerations encompass whether the bulb can tolerate voltage fluctuations, protections against electrical surges, and consistent filament illumination without flicker or instability.
Sample Evaluation Plan
Obtaining and testing samples prior to large-scale purchase reduces risk and confirms product suitability. Evaluate the TITK bulb by installing it under real or simulated use conditions matching intended environments. Observe filament glow consistency, red-light color consistency, and verify that illumination matches aesthetic expectations without flicker or color shifts during extended operation.
Have qualified personnel conduct electrical tests under an agreed test plan to validate compatibility with your specific DC power sources. Measure actual current draw, verify voltage stability during startup and steady-state operation, and check for any abnormal heat generation that might affect fixture safety or bulb longevity.
Perform a thorough mechanical inspection covering glass integrity, base mounting accuracy, and installation ease. The bulb should fit smoothly into your fixtures without undue force or wobble.
Simulate environmental stresses such as vibration, temperature cycling, and humidity exposure to anticipate durability challenges in your installation context. This may involve testing in climate chambers or real environmental conditions approximating your end-use scenarios.
Assess packaging as part of the sample review. Packaging should provide adequate protection against shocks and impacts during transport, feature labeling with clear product identification, voltage ratings, and safety instructions. If retail presentation is crucial, evaluate the aesthetics and branding potential of the packaging design. Confirm that packaging complies with shipping regulations for fragile goods and any applicable international transport standards.
Feedback from installers, electricians, or end users during the sample phase adds valuable insights into handling, installation, and operational experience.


Purchasing and Packaging Checklist
When proceeding to order, ensure all specifications match confirmed needs. Verify the SKU: TT-ST64-E27-2W-RED-CL-D-DC3-3.7-5V, shape ST64, glass type clear, base E27, power rating 2W, color red, lumen output 80, CRI 80, and voltage rating DC3/3.7/5V as per your initial requirements.
Request formal documentation on safety certifications, test reports, and quality assurance records applicable to your target market.
Clarify ordering conditions such as minimum order quantities, lead times, payment terms, and return or defect policies.
Confirm quality inspection procedures performed by the supplier and inquire about third-party testing availability if critical.
Discuss packaging specifics in detail. Agree on individual cushioning and protective materials appropriate to the shipment. Review the carton construction and validate protection under the chosen transport conditions, rather than assuming a particular packaging format is supplied. Packaging labels should clearly identify product model, voltage, wattage, and safety details.
If branding or differentiation in retail is desired, explore custom packaging options and confirm supplier capabilities, costs, and lead times for this customization.
Check that packaging aligns with international freight requirements, including hazardous material declarations if applicable, and consider durability in transport modes such as air, sea, or road freight.
Plan for inventory management with packaging formats suitable for warehousing and distribution in your channels.
FAQs
Can this bulb be used on standard AC mains power?
The bulb’s specified voltage is DC3/3.7/5V, indicating it operates on low-voltage DC power. Using it directly on AC mains may be unsafe or cause failure. Confirm with your supplier if AC adapters or compatible drivers are available or recommended.
Is the bulb dimmable?
The product library describes the bulb as dimmable. Confirm the specific control method, compatible driver and tested operating range with TITK before using it in a dimming system; this label is not a promise of compatibility with every dimmer.
What is the expected lifespan?
Request the model-specific lifespan test conditions and supporting results from TITK. Agree on any warranty and replacement terms in writing rather than treating an unverified lifespan figure as a guarantee.
