Hi everyone, my first post on Candle Power Forums.
My two business partners and myself currently design high powered LED architectural/architainment lighting, mainly in RGBW but also some white models.
We are looking at designing a high powered flashlight. Having many years experience with LED designs, we are amazed at some of the claims of LED flashlights, especially high powered flashlights over 4000 Lumens. If I may, I have some questions I'd like to ask and have your honest opinion. These questions are mainly for those who have high power flashlights, say 4000 + Lumens.
I hope at least a few people can answer some of the questions, it would be greatly appreciated.
Regards,
Jason

- If left on full power for an extended period of time, is the casing too hot to touch?
- Do you notice the light output dimming if left on high power for extended periods of time?
- Do you believe the manufacturers claims of the Lumen output?
- Do the batteries last the specified time?
- If using a fixed lens or reflector, is your preference wide or narrow beam?
- Would you find it useful to have a very detailed specification sheet to have a better understanding of the design? Example would be the battery charge and conditioner specifications (for internally charged batteries). Another example would be "how the Lumen output is calculated?
- Would you purchase a flashlight that has an IP68 (waterproof) built in fan that would ensure the LED would always run at full power when required and would also keep the casing cool.
- Would you be interested in a high end, 7500 Lumen flashlight with a 1 minute 10,000 Lumen burst mode?
I hope at least a few people can answer some of the questions, it would be greatly appreciated.
