My boss is searching for small LED lamps for bollard & other lights. Roughly 100 watt equivalent. The slimmer and shorter the better. Our supply house often has nothing. Any good online suppliers out there?
Define "small". A19 medium base, or A15, or tubular shape rather than bulb shape? My guess is that 1,500 lm class screw-in bulb for totally enclosed application that consistently offers rated life under typical field conditions still don't exist. Especially not in socket base integrated LED ballast design.
If you're asking for small, I assume small space. Even 60W equivalent struggles with heat in pancakes. 100W lamps are 15-16W or double the input of 60W equivalent. Those that actually live 10,000 hours plus are often the result of the burnout protection activating dimming to prevent frying out the ballast or the LED elements. Those bulbs are great for motion activated lights, because you still get full output for a few minutes and restore the full output during off cycle but when they're left on, they throttle down and no longer remains at the full output.
When you find some knock off brand offers what you're looking for and specs on paper looks promising, but no reputable brand offers it, the above technical limitations are why.
Those issues are less of a concern with permanent LED luminaires, because they can easily thermally bond the LED elements and their ballast to the fixture housing.
