FAQ What components are included in the standard SLL-3004 package? The SLL-3004 is supplied as a complete self-contained 70cm lawn bollard luminaire including the optical head, stem sections, ground spike, and internal battery. External tall street lighting poles are excluded; no separate pole purchase is needed. How does the SLL-3004 perform during prolonged cloudy or rainy periods? Powered by an integrated 9.6Wh Grade-A LiFePO4 battery pack and intelligent PWM power management, the SLL-3004 maintains over 3 continuous cloudy or rainy days (3+ full nights) of illumination without supplementary sunlight charging. Where is the CAD engineering blueprint for the SLL-3004 located? Because the SLL-3004 is an engineered single-model 70cm architectural bollard, its official CAD dimension blueprint is featured directly in the Product Overview media preview above for immediate architectural reference. Can the color temperature be switched between 3000K and 6000K? Yes. A discreet silicone-sealed pushbutton switch under the luminaire head collar allows contractors to effortlessly select between 3000K warm white and 6000K daylight white prior to or following installation. ![](https://static.tpk-led.com/images/website/tpk-led/Product/SLL-3004/sll-3004-hero-01.webp) Image unavailable · original image link retained ## Discovery - Site index: [https://www.tpk-led.com/llms.txt](https://www.tpk-led.com/llms.txt) - Section index: [https://www.tpk-led.com/products/llms.txt](https://www.tpk-led.com/products/llms.txt)
