Has the bulb been tested or demonstrated in poultry barn environments?
If yes, have results been released to the public?
What was bird behaviour under the lights? A consistent observation by producers with LED bulbs is that the birds behave more calmly, even when the light level is raised from dim to full light. A possible reason is that LED light does not flicker compared to CFL bulbs, which can flicker at a level noticeable to the birds. Poultry have keen eyesight and are much more sensitive than humans to light flickering.
Is there any information available regarding bulb efficiency and long–term lumen output or lamp lumen depreciation (LLD)? Do the bulbs have an Energy Star rating from third party testing? If applying for rebate programmes for LEDs, it is important to confirm if the Energy Star rating is required or if only certain types of lamps qualify.
Have bulbs been cleaned under typical poultry barn wash–down procedures? Bulbs with an IP65 rating are actually rated for wash down.
