Hey,
I've been enjoying my new Deluxe LaserBee I power meter the last few days, and here are my measures of all lasers I bought from commercial companies (so far...
), especially made for posting in LPF.
This is not a review of these lasers and companies, any other aspect of product (beam/optics quality, battery consumption, etc.) or of dealing with them (delivery, service, price, etc.) is not mentioned here.
Just dumping the numbers with some technical comments (I think everyone here knows about Wicked Lasers -
, this is just more "evidence").
I think it's important that companies know that every laser they ship may be measured with the results posted on public forums, this would certainly make them think twice before selling under-spec products (either by mistake or intentionally).
For each of these lasers I mention the advertised average output (minimum) and maximum output provided by the seller, though in some cases one of these parameters is unknown.
Notes:
- All batteries were fully charged (or fresh alkaline batteries in case of WL).
- The laser meter is calibrated.
- I have repeated each laser measure at least one more time and got similar results.
- Every measure is around 2.5-3+ minutes, after the laser was off for a long period of time.
- I've had those lasers for about a year now, but they are not excessively used and are kept with fanatic care, so they should be giving the same output (or almost) as the day I received them.
Deal Extreme Dilda 200mW Red:
The output seems to stabilize below 200mW at about 190mW, and the laser became warm.
Dragon Lasers Spartan BP-20 Blue:
The output is not stable but doesn't seem to decline over time either. It seems Dragon Lasers are aware of that since they advertise it as average between 20-30mW.
Indeed it stays in this range and sometimes goes above it.
Note: This is a pulsed laser, the meter shows an average including the "off" intervals between pulses (otherwise output would show higher I presume).
Lazershop UK BluRay Pen 20:
Wicked Lasers Elite-150 Green:
WL actually imply that it averages on 187mW in their web site showing a pretty graph which is not related to reality (in my case at least).
Wicked Lasers Executive-55:
A very clearly declining graph, the laser gets warm with time and it seems correlated.
There was no point in continuing the measure since the meter minimum power is 5mW... ;D
Wicked Lasers Pulsar 125:
Excel files also attached.
Good night everyone, it's sleepy time for me now,
