Fluorescent Lamp 5W
Fluorescent Lamp 5W (Product Code: SLE/M/64) is a compact replacement fluorescent tube with a square centre connection and wire posts on its sides, used as a spare light source for fluorescent-lit microscopes and small specimen illuminators in teaching laboratories. Measuring 4 1/4 in long and 1 1/4 in wide, it suits small lamp housings where a dim or flickering tube has to be changed quickly. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with its other microscope lighting spares.

What Is the Fluorescent Lamp 5W Used For?
Fluorescent lighting gives a cool, even glow that many student microscopes and small illuminators use to light slides without warming the specimen. Over time a tube dims, darkens at the ends or starts to flicker, and the image becomes hard to read. Replacing it with a matching compact tube restores clear, steady lighting for practicals on cells, tissues and microorganisms; keeping one or two in stock is sensible for any lab that runs several fluorescent-lit instruments.
Switch off and unplug the instrument before opening the lamp cover, and let the old tube cool. Note how the square base and side posts sit in the holder, remove the old lamp gently and fit the new one the same way round. Fluorescent tubes contain a small amount of mercury, so handle them carefully, do not break them and dispose of used tubes through an e-waste or lamp collection point.
What to Specify When Ordering
- Voltage and wattage marked on your existing lamp or lamp housing
- Base style and length, to match the 4 1/4 in square-base tube
- Microscope or illuminator make and model
- Number of spare tubes required
