High-Output Halogen for Specialised Optics

The OSRAM FRK halogen bulb delivers 16900 lumens at 3200K with a CRI of 100. It operates at 650W and 120V using a GY9.5 bi-pin base. Rated life is 200 hours. The T7 envelope suits dental, fibre-optic, microscope, ophthalmic and projection instruments needing precise colour rendering.

Thermal Behaviour and Power Profile

The lamp draws a steady 650W and emits significant heat typical of high-wattage halogen sources. Cooling must be managed by the host instrument's ventilation or forced-air system. Acoustic output depends entirely on the equipment's fan design; the bulb itself is silent. Power factor is resistive with no inrush mitigation built in.

Integration Requirements and System Impact

A GY9.5 socket rated for 650W at 120V is mandatory, along with wiring and insulation suited to the thermal load. The 1.26 in working distance aligns with optical trains designed around that focal point. The 200-hour lifespan demands scheduled replacement planning. No ballast or driver is required, simplifying the electrical chain.

Questions about this item

How do I install the GY9.5 bi-pin base without cracking the quartz envelope?

Hold the bulb only by its ceramic base, align the two pins with the socket holes, and press straight in until the pins seat fully; never touch the glass envelope because skin oils create hot spots that shorten the 200-hour rated life.

What maintenance or replacement will this 650 W halogen lamp need after its rated 200 hours?

The filament will reach end of life at roughly 200 hours; replace the entire bulb — there is no user-serviceable part and no separate filter to clean.

At what point does the 3200 K colour temperature begin to shift during continuous operation?

The 3200 K output is stable for the rated 200 hours; beyond that the filament degrades and colour temperature drifts, so plan replacement at the 200-hour mark.
