I have a chemical that is activated by light, and there is work published that describes this being done with an incandescent light bulb (the specific brand is discontinued), incorporated with a high pass filter. I figure that substituting the incandescent light bulb with an appropriate LED would be a much more elegant system.
Can I do this? What conversions should I keep in mind if I am making the switch? Would the energy of the photos differ if they are derived from an LED or an incandescent light bulb? If I should focus on the lumens, can I add up the lumens of multiple LEDs in an array to achieve an appropriate level of chemical activation?
The specific light bulb is a 100 W, 120 V, and 1450 Lm.
Thank you in advance!
I do not know what wavelength range you want to use for your research.
Just some advises for your reference
First, for an incandescent light bulb, the emission band contains plenty of near-infrared light.
For a conventional LED lamp, most of the emission band is in visible light region.
Another one is that the LED lamp contains more blue light that the incandescent light bulb.
If these two differences do not affect the chemical reaction, or you can use filter to obtain very identical emission spectra between the two light sources. You can try to substitute an LED for an incandescent light bulb.
You can add up the lumens as long as anything else is not changed. Using a LED array instead of a single LED usually increases the width of the light source. If the larger light source dimensions can be compensated with lens or reflector optics, you can approximately add up the lumens. You may also use a high power single chip LED giving upto 4000 lm, e.g. SST90 from Luminus.
