R7s LED – 5W

The R7s LED 5W is a 78mm J78 double-ended lamp that drops straight into a T3 halogen holder. No driver, no conversion kit, no rewiring.

It draws 4.8W measured, runs on any supply between 100V and 140V, holds CRI above 80 at 3000K, and it dims.

Seventy SMD 2835 diodes, ETL listed under Intertek file 5002042, rated for 25,000 hours and backed by a 3 year warranty.

Can I replace an R7s halogen with LED?

Yes, and it's a direct swap. R7s runs at line voltage in Canada, so there's no transformer to remove and no conversion kit to buy. Cut the power, let the old capsule cool, spring one end into the holder and seat the other.

In Canada this is an energy decision, not a compliance deadline. The prohibition that took effect on 2026-01-01 covers mercury-containing fluorescent lamps, CFLs and linear tubes. It says nothing about halogen, and R7s capsules are still legal to sell here. The EU is where mains-voltage halogen came off the market, on 2023-09-01, and that rule keeps surfacing in Canadian results where it doesn't apply.

Is R7s the same as T3?

They describe different things about the same lamp. R7s is the base, the recessed single contact at each end. T3 is the envelope, a tubular glass three-eighths of an inch across. J78 is the trade code, where J means double-ended and 78 is the length in millimetres.

All three name this lamp. The number is what you have to get right. A 78mm lamp won't bridge a 118mm holder. Measure the holder, not the old bulb's label.

Why the 100-140V input range matters

The 2024 revision widened this lamp from a fixed 120V to AC100-140V. On a long run, a loaded panel or generator supply, a 120V-only lamp dims and flickers as the voltage sags. This one holds its output across a 40 volt window, which is the difference between a callback and a clean handover.

Where it fits, and where it doesn't

IP20, dry locations only. Keep it out of damp and wet locations, exterior floods and sealed outdoor housings. It runs from -20°C to +45°C, best near 25°C, in 40 to 90% relative humidity.
