R7 LED Bulbs — Linear Floodlight Replacement

R7 LED Bulb

R7 LED bulbs are high-output linear lamps used in floodlights, security lights, and uplighter fittings. Lumination stocks R7 LED linears from Lampfix and Magnalux in 78mm (J78) and 118mm (J118) lengths, replacing 150W–500W halogens with outputs of 1,500–5,000 lumens at a fraction of the energy.

R7 LED Linear Bulbs — Replacing Halogen Floodlight Lamps

R7 linear lamps fit the double-ended J-type socket found in outdoor floodlights, work lights, and large indoor uplighters. The two standard lengths are 78mm (J78) and 118mm (J118) — confirm your fitting's lamp length before ordering. A 20W R7 LED delivers approximately 2,000 lumens, replacing a 150W halogen at 87% lower energy. Lumination stocks R7 LED linears from Lampfix and Magnalux with confirmed lumen data for each length and wattage.

R7 LED Bulb Sizes and Lumen Output Guide

78mm R7 LED bulbs typically replace 100W–150W halogens; 118mm R7 LEDs replace 300W–500W halogens. Always measure the physical length of your existing lamp before ordering. R7 LEDs are not dimmable in most cases — confirm the product specification if dimming is required. Browse the full LED bulb range for other high-output formats. For outdoor security lights and outdoor wall lights, Lumination's team at the Taunton and Wellington showrooms can advise on the correct R7 length and output for your fitting.

Frequently Asked Questions

R7 linear LED bulbs come in two standard lengths: 78mm (J78) and 118mm (J118). The length refers to the physical lamp length between the two end caps — you must match this exactly to your fitting. A 78mm R7 fitting will not accept a 118mm lamp, and vice versa. The wattage and lumen output available also differs between the two lengths: 78mm R7 LEDs typically cover 10W–20W outputs; 118mm R7 LEDs cover 20W–50W outputs for higher-lumen applications. Lumination stocks both lengths from Lampfix and Magnalux. Our team at the Taunton and Wellington showrooms can help confirm the correct lamp length for your floodlight or uplighter fitting.

A 300W halogen R7 linear produces approximately 4,500 lumens. An LED R7 delivering equivalent output typically draws 30W–35W — a saving of around 90%. Lumination recommends cross-referencing lumen output rather than wattage equivalences, as different LED manufacturers quote different output figures for the same wattage. Lampfix and Magnalux R7 LEDs in Lumination's range provide confirmed lumen data on each product listing, so you can verify output before purchasing. With 1,797+ Google reviews at 4.8 stars and 25 years of specialism in residential and commercial lighting, Lumination ensures accurate product specifications across all bulb ranges.

Most R7 LED linear bulbs are not dimmable due to the integrated driver design. A small number of R7 LED variants support dimming — these require a compatible mains-voltage LED dimmer and are clearly labelled as dimmable in the product specification. If dimming is a requirement for your installation, confirm dimmability before purchase. Lumination's Lampfix and Magnalux R7 LED listings indicate dimming compatibility clearly. Standard R7 halogens are fully dimmable on a leading-edge dimmer, so switching to a non-dimmable LED R7 will mean the dimmer circuit needs replacing or bypassing. Lumination's team at the Taunton and Wellington showrooms can advise on the best approach for your installation.

R7 LED linear bulbs can be used in outdoor floodlight fittings provided the luminaire itself is rated for outdoor use with an appropriate IP rating — IP44 minimum for exposed locations, IP65 for areas subject to direct water spray or rain. The R7 LED bulb itself does not carry an IP rating; it is the luminaire housing that must meet the IP requirement for outdoor installation. Lumination stocks a range of outdoor floodlights with integrated or replaceable R7 lamps. Always confirm that the floodlight fitting is IP-rated before installing an R7 LED in an outdoor environment. Browse Lumination's outdoor floodlight and security light collections for IP-rated options.

For an outdoor security light or floodlight using an R7 linear lamp, 1,500–3,000 lumens is appropriate for residential driveway and garden illumination. Larger areas such as car parks or commercial yards typically require 4,000–6,000 lumens per fitting. A 20W R7 LED delivers approximately 2,000 lumens — suitable for a standard residential driveway or pathway. A 30W–35W R7 LED delivers 3,000–4,500 lumens for wider coverage areas. Lumination stocks R7 LED linears from Lampfix and Magnalux with confirmed lumen output for each wattage. With 25 years of lighting specialism, Lumination can advise on the correct output level for your specific outdoor security application.
