Do you know that most branded microscope manufacturers stop supporting their illuminators after 5-7 years of production? This means that if your microscope is that young and the halogen illuminator goes out, it's likely that the illuminator and parts are no longer available.  At this point you have just two options. You can buy a new microscope and send your scope to Surplus Inventory to sit on a shelf. Or, you can join the ranks of hundreds of our satisfied customers and replace the illuminator with our LED illuminator at a fraction of the cost!

Much of the time when a microscope starts burning out allot of bulbs or just quits working, the problem can be a bad printed circuit board (pcb). In order to keep the scope operational if the model is newer than 5 years you would need to replace the printed circuit board (if still available for approx. $800). Or, you could just buy a new microscope which will have an LED illuminator in it.

Now, Answer This. Would having to replace a microscope (not on the budget) create a problem for your lab? If you’re like allot of clinical and research labs around the country – it could be a crisis.  We know, because our company is in those labs every day. We sell and service major brand microscopes and have been for nearly 30 years. Replacing one microscope at $7-9k is bad enough for most labs.

Recently, one of our hospital labs that has over 20 working microscopes in service had 4 scopes that went out of commission due to defective pcb’s. To replace those four scopes would be 4 x $7k or $28,000. That can be a financial problem for some of the more prosperous labs.  

Fortunately, we came to their rescue with 4 LED illuminators.  The good news is, it only cost them $1995. And they installed them very quickly: three minutes per scope without any tools!

Our LED replacement illuminators are rated at 50,000 hours which is longer than the lifetime of the microscope! Your will never replace another bulb or board or component on a board! Guaranteed! 

Very Easy to replace the original halogen or tungsten lamp house. Installs in less than 5 minutes - without any tools! It works very well in ALL microscope techniques (phase contrast, polarization, etc.) since it is Daylight intensity and color balance.
