If there is something that gets my emotions up & running it is LED's! ..I love them with a passion, the changes in efficiency every 4-6 months has me all twitchy, as a young lad working with them ( were not used for anyhting other than standby switches, so investment into technology had stalled years back) they were a very exciting form of low cost lighting with a great burn time when constructed correctly, I still remember the day I first understood the advances led could give us if utilised, took another 20 years to really start to come good.
When looking at an led you need to know what module is being used, the measuring process & manufacturer putting it into production, as they all hinge on each other a bit like an energy consuming oven or a low energy efficient well designed model.
Why care? because it's all got to be produced, manufactured, shipped, packaged, retailed etc, all along the way that involves multiple packaging.
I only like to buy once (as in a lifetime product purchase).
By getting aquainted with a few of the specialist led selling sites you can learn a lot about various modules efficiency / drain etc & look out for those sets within product, the cheap bargain bucket end of the markets mechanical tolerances are far more finite than one would imagine coupled with poor production technique, poor light output matching & measuring.
If considering something with multiple leds to stick in your pumpkin that is actually a light for sticking under parasol round a table outside at night that may cost $15 -$20 bucks per unit go into a camping / outdoors shop & see what they've got for a bit more to maybe double in terms of led utility lighting instead, that way your purchase isn't simply (possibly) cheap crap with limited use.
For instance I purchase Black Diamond Apollo lanterns (50 / 56 lumen) when I travel abroad which (could be better) run on 4 AA's & have a variable light output, the led emitter being a quality unit, & just in the process of being upgraded to 80 Lumen (so check stock) ..the result is that this is a well designed unit of plastic, rubber, & metal, water resistant, pumpkin guts resistant, & useful for the rest of the year as utility / camping lighting, a fab nightlight for my daughter which we stick on lowest setting by her bed (has alot of nightmares) ..great power out light, plenty of reviews on it.
OK so it costs more but they are used every week, durability of a well known outdoors brand, fits in a pumpkin, diffused light ideal for illumination.
if you need a stable adjustable light i'd highly recommend one as a gift for an outdoorsman or dad who crawls around in attics doing repairs, very multi-modal.
(theres also a 1 watt version which is really tiny called the "orbit")
Take the rrp witha pinch of salt theres alot of variables with places such as mountain co-op in canada etc.
Torch forums are also a good place to learn about the stock unit led's being used too!

This link (below) is to candlepower forums so deconstruction of the lamp & alot of basic info on why only decent light emitters...

No, i'm not back.
