Hi guys thinking about running some CMH bulbs bare dude to shortage of space between fixtures and I want the most even spread of the spectrum possible.

So my question is:
if I run my CMH bulbs bare will the UV they putoff damage my LEDs or the PCB and degrade their output or efficiency?

Are your leds enclosed in a fixture of some sort? If so it’s just the metal outside box and the stuff that’s important is inside. You should be good. Show us a pic

No my LEDs are bare bridgelux strips. The diodes are naked

cmh bulb with outer glass envelope intact doesn't put out enough UV to damage the pcb, diodes, etc.

No worries, Happy growing
