LED Light Indicator
LED Light IndicatorAn innovative replacement for torch bulbs in circuit studies. The unit uses two parallel LEDs to give ultra long life.
LED Ray Box
LED Ray BoxA classic ray box for ray tracing in optics experiments. The light source is a high intensity white LED which runs at low temperature. Ships with removable slit plate and lens to provide one or three parallel rays.
LED Stroboscope
LED StroboscopeThe Lascells LED stroboscope is a compact microcontroller timed strobe lamp suitable for prolonged operation. The lamp is a bright 1100lm 20W LED and is separate to the control unit on a 1.2m lead.

Lenz’s Law kit, U-profile
Lenz’s Law kit, U-profileLenz’s Law is demonstrated in this apparatus by allowing a magnet to roll down a nearly vertical aluminium U-profile.
Lenz’s Law Demonstrator
Lenz’s Law DemonstratorProvides a convenient method of demonstrating Lenz’s Law.
Leslie’s’ Radiation Plate
Leslie’s’ Radiation PlateThis apparatus allows the demonstration of the dramatic differences in radiated heat from various surfaces. Being electrically heated it is more convenient than some of the more conventional methods involving water or Bunsen flames.
