bonsaiTALK Community - View Single Post - HID Light Longevity and Spectrum Question

Thanks for the link, Matt. I have read Jerry's materials before - but he doesn't spend much time on the useful lifespan of MH bulbs for trop and subtrop bonsai applications, or on the variations I now find in different brands of MH bulbs and color spectrums (i.e., the blue vs. red vs. white thing...).

dtree - any opinion on the two bulbs I am currently using vs. the Philips ceramic White bulb? I have a 600W Sunmaster Cool Deluxe MH Conversion Bulb, and a 1000W BT37 Sunmaster Blue Burning Metal Halide Lamp with about 2500 hours used up on each.

Thanks!

Tom
