sTube is a complete LED lighting fixture with an externally led power supply and control unit. It has been designed for a highly cost-effective operation and an extraordinary light quality. It is the essential element in most Snaggi products. The final product is assembled in the Czech Republic at Snaggi.

sTube achieves the lowest total costs of lighting bar none, everywhere where lighting is used frequently and for prolonged periods of time. The initial investment in sTube lighting is quickly returned in the form of reduced energy consumption and practically no need for maintenance.

sTube produces gentle light and offers a higher contrast and lower eye strain. A wide range of operating temperatures, easy installation and true colour presentation enable its versatile use in indoor as well as outdoor environments.

sTube in practice

Differences of sTube


Lights are available in 4 lenghts: sTube mini (13,5 cm), sTube 55 (55 cm) , sTube 110 (110 cm), sTube 135 (135 cm) viz. specification .

Light spectrum

Snaggi sTube

a fluorescent lamp

ISO 3664 / Certification of quality and accuracy of color reproduction for visual inspection of materials

Colour rendering index

Colour rendering index Ra is the fidelity evaluation of color perception, caused by light from any light source, compared to color perception created by the sun. The value of Ra can be from 0 to 100. Value Ra=0 means, that we can't distinguish colors in this lighting. On the other side value Ra=100 means, that we are using light source, which enables natural color reproduction.

Light output degradation and lifetime

Comparsion of Snaggi LED sTube and T8 fluorescent tube (average L70 Extrapolation).

Test report LM-80 according to the methodology TM-21 / lifetime certification and degradation rate


Snaggi has been used unique light reflective nano foil in luminaries to reach even diffusion and softening of originally too hard LED light. Total reflectivity of the foil 99%, diffusing reflection 96%, mirror-reflection 3%.
