The Philips TrueForce Core LED Road 40W 730 E40 MV LED bulb, reference 31633100, is a professional lamp designed to modernize lighting fixtures equipped with SON-T sodium lamps. With just 40 W, it delivers a luminous flux of 7200 lm and a high efficacy of 180 lm/W, offering a LED alternative to 100 W SON-T lamps.
Equipped with an E40 cap, warm 3000 K light and a wide 330° beam angle, it is especially suited to street, urban and outdoor lighting renovation projects. It operates directly on a 220-240 V mains supply, without an electromagnetic ballast, features IP65 protection and offers a nominal service life of 25,000 hours.
The Philips TrueForce Core LED Road delivers 7200 lm with a nominal consumption of 40 W, achieving a luminous efficacy of 180 lm/W. This high efficiency makes it possible to significantly reduce installed power when replacing conventional discharge technologies.
Philips specifies it as a direct LED alternative for applications previously fitted with 100 W SON-T lamps, provided the luminaire is compatible with its dimensions, thermal characteristics and electrical system.
Reference 31633100 is specifically developed as an alternative to 100 W SON-T high-pressure sodium lamps. Its tubular format and practically omnidirectional light output make it possible to take advantage of the optics and reflectors of many luminaires originally designed for HID sources.
Before replacement, it is necessary to check the cap, the available space inside the luminaire and the existing electrical configuration.
This TrueForce Core LED Road operates exclusively via direct connection to the mains. Philips specifies ballast compatibility as mains only, so it must not be used while keeping the electromagnetic ballast of an existing SON-T installation in series.
When used as a replacement for a discharge lamp, the existing control gear must be bypassed or removed according to Philips installation instructions. Any wiring modification must be carried out by a qualified professional.
The lamp uses an E40 screw cap, common in professional and high-power street lighting luminaires.
Philips offers different TrueForce Core LED Road variants with different caps, wattages and color temperatures, so the exact reference should always be checked before replacing an existing lamp.
The 730 color code corresponds to a color temperature of 3000 K and a CRI of 70. This tone provides a warm white light especially suitable for urban, residential and outdoor areas where a less cold lighting appearance is desired.
The color consistency specified by Philips is below 6.
The TrueForce Core LED Road has a nominal beam angle of 330°. This very wide light distribution allows light to be emitted around practically the entire perimeter of the lamp.
Its behavior makes it easier to take advantage of existing reflectors and optics in compatible luminaires originally designed for tubular discharge lamps.
The lamp has a tubular shape with a transparent glass body. Its diameter is 46 mm and its total length is 225 mm.
These dimensions should be checked before installation, especially in enclosed luminaires or those with limited internal space.
Philips expressly states that this lamp can be used inside enclosed luminaires. However, the thermal and installation conditions set by the manufacturer must be respected to ensure proper operation and service life.
The lamp itself has an IP65 protection rating, offering protection against dust and water jets within the conditions indicated by Philips.
In outdoor installations, the overall protection will also depend on the luminaire, lampholder, connections, cable glands and the rest of the assembly components.
The current Philips datasheet specifies a nominal service life of 25,000 hours. Lumen maintenance at the end of nominal life is 70%.
The lamp is also designed to withstand up to 50,000 switching cycles.
LED technology provides lighting almost immediately after switching on. The nominal start-up time is 0.5 seconds and the time required to reach 60% of luminous flux is also approximately 0.5 seconds.
This is an advantage over certain discharge technologies that require a warm-up period before reaching full light output.
The lamp operates with a nominal supply of 220-240 V and a frequency of 50-60 Hz. Its nominal current is approximately 178 mA and it has a power factor of 0.9.
It is designed for direct mains connection and is not compatible with dimmer control.
For sizing installations with multiple lamps connected directly to the mains, Philips specifies the following maximum values:
These values should be considered together with the actual sizing of conductors, protection devices, line lengths and installation conditions.
The Philips TrueForce Core LED Road can operate in an ambient temperature range from -30 to +45 °C, providing a wide margin for outdoor applications.
The maximum nominal T-Case temperature indicated by Philips is 49 °C.
The lamp has energy efficiency class C according to the current European scale. The declared energy consumption is 40 kWh per 1000 hours of operation.
Philips classifies this light source within photobiological risk group RG1 in accordance with EN 62471. The declared PstLM flicker value is 1 and the stroboscopic effect indicator SVM is 2.
The Philips TrueForce Core LED Road 31633100 makes it possible to replace 100 W SON-T lamps with an E40 LED source of only 40 W and 7200 lm. Its high efficacy of 180 lm/W, 330° beam angle and tubular format make it easier to modernize compatible luminaires while maintaining a wide light distribution.
The warm 3000 K light, IP65 protection, operating range from -30 to +45 °C and suitability for enclosed luminaires complete a solution specifically aimed at urban and street lighting renovation projects.
Important: this version operates exclusively via direct mains connection. It must not be used with an electromagnetic ballast left in series. The adaptation of existing SON-T luminaires must be carried out by qualified personnel following Philips instructions.
